Enrico Olivelli updated ZOOKEEPER-714:
--------------------------------------
Fix Version/s: 3.5.7
> snapshotting doesn't handle runtime exceptions (like out of memory) well
> ------------------------------------------------------------------------
>
> Key: ZOOKEEPER-714
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-714
> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.2.2
> Reporter: Patrick Hunt
> Priority: Major
> Fix For: 3.6.0, 3.5.6, 3.5.7
>
>
> If an out of memory occurs during snapshotting we recover from the error,
> however we should be more explict about the problem.
> Currently we log a warning, really we should log a FATAL and exit. This would
> force the server to restart (supervisor) and make it very clear to the user
> there is a problem. In some cases users don't notice the OOM exception (we
> have trouble noticing it sometimes ourselves) as it doesn't stand out on the
> logs. Exiting would be more explicit. However since we'd like to remove
> sysexits due to container issues it's not clear what we should do here in
> addition to making this FATAL.
