Alfresco completely freezing on trying to empty trashcan

[darminm]

Hi,

I have an Alfresco instance that becomes completely unresponsive when trying to empty trash can via Alfresco share.
Both retrieving content that should be selected for deletion or simply clicking on Empty freezes the content.

Version is 5.0.2 on Windows Server 2012 R2.
Tomcat maxThreads=150
db connections is 275
SOLR is running on the same tomcat instance

javamelody & threaddump attached

16GB of RAM is available on the server

Java options:

-XX:+DisableExplicitGC
-XX:+UseConcMarkSweepGC
-XX:+UseParNewGC
-XX:ReservedCodeCacheSize=128m
-Djava.awt.headless=true
-Dalfresco.home=D:\Alfresco
-Dcom.sun.management.jmxremote
-Dhazelcast.jmx=true
-XX:MaxPermSize=512M
-Xms8G
-Xmx10G

How many documents are in your trashcan? If its many thousands then I suspect you are getting a timeout.

There is a trashcan emptier quartz job available on the internet which removes documents in blocks. I have a modified version of it running on V4.2e fine so I suspect it would work OK on 5.
