[jira] [Commented] (FLINK-2504) ExternalSortLargeRecordsITCase.testSortWithLongAndShortRecordsMixed failed spuriously

    [ https://issues.apache.org/jira/browse/FLINK-2504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14747333#comment-14747333 ] 

Stephan Ewen commented on FLINK-2504:
-------------------------------------

The occasional "Cannot allocate memory" means that the VM or container has not enough RAM to do the I/O operation due to Java needing off-heap memory for that.

We could try to reduce the heap size of the JVM, leaving more memory unused. Otherwise, we cannot influence this...
