Description

Currently, the accumulo startup script hardcodes OnOutOfMemoryError behavior to be kill -9 %p. Perhaps this could be modified to call a script.

for example:

-XX:OnOutOfMemoryError="${ACCUMULO_HOME}/bin/oom.sh %p $1"

whose default behavior implementation is kill -9, but this can be modified by the administrator to implement other behavior (e.g. do a jstack first).

This has the added benefit of being able to modify the behavior at runtime without restarting processes.
