Subject Re: Active MQ Automatically Getting Restarted
Date Wed, 24 Jan 2018 14:01:41 GMT
What garbage collection algorithm are you using? If it's CMS, it's possible
to get an OOM even though there is heap space still available.

What limits do you have configured on the memory store, and what percentage
is used shortly before the OOM occurs?
