[jboss-jira] [JBoss JIRA] (JGRP-2403) Dump information in panic scenarios

[Bela Ban (Jira)]

     [ https://issues.redhat.com/browse/JGRP-2403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban resolved JGRP-2403.
----------------------------
    Resolution: Done


Thread dumps are done only *once*: when the pool is full for the first time.
Once {{thread_dump}} is reset, next time around another thread dump will be logged at FATAL level.
To enable the next thread dump: {{probe.sh op=TP.resetThreadDump}}

> When there is a panic situation (e.g. thread pool exhausted), dump information (e.g. including a thread dump) to a file at FATAL level. 
> The question is *when* do we do this? If the pool fluctuates between almost-full and full, we can't obviously take a thread dump every time!
