What causes the mutation data panel load to fail and then load properly after a page refresh (sometimes several refreshes)?We have a local cbioportal instance. When we try to load to local studies, 1 a little over 11k samples, the second ~1.2k samples.We are trying to track down what causes the failure to load. Have increased memory from 32G to 64G, increased amount of memory available to tomcat and still we are having issues. W'd like to correct this prior to rolling out to our users.

1.15.1-SNAPSHOT
It was downloaded by default when we first installed the portal a couple of months ago. Will update our version to the latest and greatest.
Thanks,
John

Hi John,
this could be a limitation of an old version. Which version are you using?
The scenario I see is: the processGetSmgRequest is maybe called via a GET request. If this is the case, there is a limitation on the number of parameters (so in this case samples) it can handle (because there is a limitation to the size of the URL). This limitation would explain why the NullPointerException occurs specifically at org.mskcc.cbio.portal.util.InternalIdUtil.getStableSampleIds(InternalIdUtil.java:47): most likely the caseIds in the URL parameter is getting truncated, which causes one of the case ids (aka sample id) to be invalid and not found in the DB, making the line Sample s = DaoSample.getSampleById(internalSampleId) return null which will cause the subsequent line with s.getStableId() trigger a NullPointerException since s is null.
But again, I expect this to be very old and dead code by now. It looks like you are using an old version of cBioPortal, correct?
Best,
Pieter Lukasse
