[jira] [Commented] (IGNITE-17807) OutOfMemoryException in RebalanceIteratorLargeEntriesOOMTest on TC

["Roman Puchkovskiy (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-17807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17619434#comment-17619434 ] 

Roman Puchkovskiy commented on IGNITE-17807:
--------------------------------------------

# On my machine, 256Mb of heap is enough for the test to pass
 # The test was passing with 256Mb on TC before TC migration
 # The same test passes with 256Mb in Gridgain-CE (on different TC installation)

So it seems that TC changes triggered failures, maybe due to slower disk subsystem: 256Mb is simply not enough.

So the proposed fix is to raise heap size to 512Mb.

> The OOME exception seems to be thrown by the remote JVM, which is probably of version higher than 8 (probably 17, see IGNITE-17805).
> The TC build contains a heap dump, but judging by its size (5.3Gb) and the configuration for the remove JVM (-Xmx256m), the dump is made on the original JVM that runs the test, so it is not relevant to the issue (as the OOME happens on the remote JVM).
