Henrik Karlsson updated AMQ-5328:
---------------------------------
Summary: Store limit reset to a smaller value than the current size
(was: Store limit reset to a smaller value then current size )
> Store limit reset to a smaller value than the current size
> ------------------------------------------------------------
>
> Key: AMQ-5328
> URL: https://issues.apache.org/jira/browse/AMQ-5328
> Project: ActiveMQ
> Issue Type: Bug
> Components: Message Store
> Affects Versions: 5.9.0
> Environment: Windows Server 2012
> Reporter: Henrik Karlsson
>
> 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 block 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
