Morning all.
Wicket 7.6.0
Tomcat 8.5.11
Java 1.8.0_121
I'm seeing several DiskDataStore Exceptions [1]. Normally towards the end
of the day, long after users have stopped using my app. So probably when
their sessions time out.
The file name looks very suspicious to me.
/opt/starjar/domains/customer/apache-tomcat-8.5.11/work/Catalina/localhost/Starjar/Key[type=org.apache.wicket.protocol.ws.javax.JavaxWebSocketFilter,
annotation=[none]]-filestore/247/7021/D69E0EE552DC1F1FE5FF986A1A919C39/data
Another perhaps unrelated exception [2]
Any pointers where I should dig to solve this ?
Thanks
Peter
