[jira] Commented: (UIMA-1789) deployAsyncService script should use -XX:+HeapDumpOnOutOfMemoryError

["Eddie Epstein (JIRA)" <de...@uima.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-1789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12873996#action_12873996 ] 

Eddie Epstein commented on UIMA-1789:
-------------------------------------

A problem with enabling heap dumps as the default is that many large files can accumulate for unsuspecting users. To me, enabling heaps dumps is something done specifically when looking for problems, not a typical default configuration. It would be nice to hear other opinions on the matter.

> In case a user application needs to much memory an OuOfMemoryError stops the UIMA AS service. It would
> be nice if the VM would just dump the memory for further analysis and stops afterwards.
> For a sun vm this can be achieved with this command line option:
> -XX:+HeapDumpOnOutOfMemoryError
> Can this be done in our script, does it also work with other VMs ?
