[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=12872341#action_12872341 ] 

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

The process (UIMA service) created by deployAsyncService picks up custom JVM parameters from the environmental parameter UIMA_JVM_OPTS. If this parameter does not exist, the default is "-Xms128M -Xmx800M".

Does this resolve the issue?

> 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 ?
