> We have a cluster setup using "Shared File System Master Slave". The kahadb database
is stored on a 20 GB shared filesystem. The last weeks we have had a couple of times where
producers where stopped because the persistent store usage was at 100%. I found that where
about 8 GB of disk available, so the persistent store usage shouldn't be more than around
60%.
> I found that when starting up or failing over the max size of the persistent store is
adjusted to be no more then the available disk space. Found this in the log:
> INFO   | jvm 1    | 2014/07/27 06:36:09 |  WARN | Store limit is 20480 mb, whilst the
data directory: \\pulbrscbfs1\ActiveMQ\kahadb only has 7945 mb of usable space - resetting
to maximum available disk space: 7945 mb
> And then this occurs:
> INFO   | jvm 1    | 2014/07/27 06:40:03 |  INFO | Usage(default:store:queue://PCIS.SCH.Notes.Jobs:store)
percentUsage=153%, usage=12813873606, limit=8331595776, percentUsageMinDelta=1%;Parent:Usage(default:store)
percentUsage=153%, usage=12813873606, limit=8331595776, percentUsageMinDelta=1%: Persistent
store is Full, 100% of 8331595776. Stopping producer (ID:PULBRSCBMULE2-49430-1406435872187-1:1:4:1)
to prevent flooding queue://PCIS.SCH.Notes.Jobs. See http://activemq.apache.org/producer-flow-control.html
for more info (blocking for: 2s)
> As you can see the percentUsage is 153%!
> So the reset of the store limit to 7945 mb is wrong and should have been 12220 mb + 7945
mb = 20165 mb
