            <title>[FOLIO-2276] Adjust memory settings source-record-storage, source-record-manager</title>

                    <description>&lt;p&gt;&lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; class=&quot;user-hover&quot; rel=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; data-account-id=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; accountid=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; rel=&quot;noreferrer&quot;&gt;Kateryna Senchenko&lt;/a&gt; reported source-record-manager was down on folio snapshot-load. After restarting source-record-manger with a higher container memory limit, the same load caused an OOMkill on source-record-storage. &lt;/p&gt;

&lt;p&gt;To remediate I&apos;d propose increasing the container memory limit in the module descriptor for these two modules, while leaving the heap size of 256 unchanged. However, I want to be mindful to not over-provision these after &lt;a href=&quot;https://folio-org.atlassian.net/browse/FOLIO-2242&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://folio-org.atlassian.net/browse/FOLIO-2242&lt;/a&gt; is completed.

I&apos;m curious to see if Java does a better job managing the burst under those conditions.&lt;/p&gt;</comment>

On a test trying to upload 5 files w/500 marc records each the source-record-manager container ends up getting OOMKilled.&lt;/p&gt;

&lt;p&gt;JAVA_OPTIONS are: &quot;JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap&quot;,&lt;/p&gt;

&lt;p&gt; For some quick and dirty logging I ran:&lt;/p&gt;

&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
&lt;pre&gt;while true
do
  docker stats --no-stream d8d2b604bc2c &amp;gt;&amp;gt; srm.txt
  sleep 1
done
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt; 

&lt;p&gt;and saw it hit the limit:&lt;/p&gt;

&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;

&lt;p&gt;Will try leaving the java options the same (no xmx) and bumping up the container limit.&lt;/p&gt;</comment>

                                                            <comment id="193313" author="557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a" created="Mon, 23 Sep 2019 11:04:48 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=5cd423bebc70090d6ce241b1&quot; class=&quot;user-hover&quot; rel=&quot;5cd423bebc70090d6ce241b1&quot; data-account-id=&quot;5cd423bebc70090d6ce241b1&quot; accountid=&quot;5cd423bebc70090d6ce241b1&quot; rel=&quot;noreferrer&quot;&gt;Ian Hardy&lt;/a&gt;,&lt;br/&gt;
10 files of 500 marc records each looks good enough, although we&apos;re aiming at loading 30 000 records at once. On Friday it was failing when I tried to upload 4-5 files of 15 to 1000 records, and it looked like it mattered how many files were uploaded, not that much the size of the file.&lt;br/&gt;
Also we identified an issue in mod-data-import  
    &lt;span class=&quot;jira-issue-macro resolved&quot; data-jira-key=&quot;MODDATAIMP-192&quot; &gt;
                &lt;a href=&quot;https://folio-org.atlassian.net/browse/MODDATAIMP-192&quot; class=&quot;jira-issue-macro-key issue-link&quot;  title=&quot;Apply blocking coordination for file processing&quot; &gt;
            &lt;img class=&quot;icon&quot; src=&quot;https://folio-org.atlassian.net/rest/api/2/universal_avatar/view/type/issuetype/avatar/10309?size=medium&quot; /&gt;
            MODDATAIMP-192
        &lt;/a&gt;
                                                    &lt;span class=&quot;aui-lozenge aui-lozenge-subtle aui-lozenge-success jira-macro-single-issue-export-pdf&quot;&gt;Closed&lt;/span&gt;
            &lt;/span&gt;
 that could result in increased memory consumption when we load multiple files. I&apos;d like to test it more (loading one big file vs multiple small files) to confirm that as soon as data-import is up on snapshot-load.&lt;/p&gt;</comment>
                                                            <comment id="193319" author="5cd423bebc70090d6ce241b1" created="Wed, 25 Sep 2019 19:04:24 +0000"  >&lt;p&gt;I increased the memory limit on SRM and loaded 1 file of 30k records (this is the test that &lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; class=&quot;user-hover&quot; rel=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; data-account-id=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; accountid=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; rel=&quot;noreferrer&quot;&gt;Kateryna Senchenko&lt;/a&gt; said failed this morning). Watching the memory usage of mod SRM I saw it peak at about 570MiB. the limit is currently configured at 682MiB which works out to aroudn 715 MB. Let me know if this seems like a reasonable limit here.&lt;/p&gt;</comment>

I did a batch of 3 files with 30,000 records, and one file of 60,000 just to test the limits of the current config. The 3 at 30,000 worked fine (now they queue up). After loading the 60,000 record file mod-inventory-storage crashed, but I&apos;ll consider that outside the scope of this issue. &lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=5af5e627525ba96b58654f12&quot; class=&quot;user-hover&quot; rel=&quot;5af5e627525ba96b58654f12&quot; data-account-id=&quot;5af5e627525ba96b58654f12&quot; accountid=&quot;5af5e627525ba96b58654f12&quot; rel=&quot;noreferrer&quot;&gt;Ann-Marie Breaux&lt;/a&gt;&lt;a href=&quot;https://folio-org.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; class=&quot;user-hover&quot; rel=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; data-account-id=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; accountid=&quot;557058:06f9b6fb-9a52-481a-ad72-6e13fc570a8a&quot; rel=&quot;noreferrer&quot;&gt;Kateryna Senchenko&lt;/a&gt; does that seem like a reasonable test, and if so, shall we leave the memory settings where there are now?&lt;/p&gt;</comment>

Is there user documentation for data import currently? If so, it would seem logical to add a section for system administrators explaining how the memory settings can be tuned to support larger record loads.&lt;/p&gt;</comment>

-verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -Xloggc:/path/to/file/gc.log &lt;br/&gt;
the same way you do it for Xmx. The log file will be created in the local file system of your container. So you can just grab it from there or you can mount an external volume to the container beforehand. if you can share those files with us it can help us to understand what is the cause of that unusual memory consumption.&lt;/p&gt;</comment>

Just to make it clear.&lt;br/&gt;
&lt;a href=&quot;https://merikan.com/2019/04/jvm-in-a-container/&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://merikan.com/2019/04/jvm-in-a-container/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;so we can reduce the memory limit for the container and use -XX:MinRAMPercentage &amp;amp; -XX:MAXRAMPercentage to allocate more memory for JAVA Heap&lt;/p&gt;</comment>

If you have specific recommendations, at this point I&apos;d suggest you:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;Validate your assumptions by running your application in a local JVM and examining the memory usage. You can run a local instance of your application with a Vagrant box using the procedure documented here: &lt;a href=&quot;https://github.com/folio-org/folio-ansible/blob/master/doc/index.md#running-backend-modules-on-your-host-system&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;https://github.com/folio-org/folio-ansible/blob/master/doc/index.md#running-backend-modules-on-your-host-system&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;Build a local container for your application with the Dockerfile in your application repository. Launch it with the settings that you want to implement, and test its behavior.&lt;/li&gt;
&lt;/ol&gt;
