Adrian Crum commented on OFBIZ-3867:
------------------------------------
One idea off the top of my head and without looking at the code would be to
give the JobManager a state. It could enter a suspended state and then try
switching to an active state from time to time. State change log entries would
be informational, not warnings.
Having a hook where outside events could monitor/trigger state changes could be
useful. A process monitoring the request load could suspend the JobManager
during peak traffic times.
> JobManager.poll() enters an endless loop when it can't get a connection

> Project: OFBiz
> Issue Type: Bug
> Reporter: Adam Heath
> Assignee: Adam Heath
>
> JobManager.poll(), line 157, where it calls storeByCondition, can fail when
> there is no connection available from the database(due to a connection leak,
> or just load, or whatever). An exception then gets thrown by
> storeByCondition(deep inside ofbiz/commons-dbcp/postgres). The
> catch(Throwable) then logs the error, and the loop tries again. Since
> pollDone never gets set to true, this loop is *very* tight, and the log file
> starts to fill up *very* fast, each each thread of JobPoller tries the same
> thing over and over.
> I'm filing this bug mainly to see if anyone else works on it, but if not,
> it's a reminder for me.
