jboss org.hibernate errors??

GoogleCodeExporter commented 9 years ago

Running jboss server / or two standalone instances for gss service, and every 
now and then errors like attached in log start appearing.
What might be causing them? Is this org.hibernate problem or postgresql 
database problem? How can it be resolved?

Jboss server(s) are running on centos 5 64bit servers.

Caused by: org.hibernate.StaleObjectStateException: Row was updated or deleted 
by another transaction (or unsaved-value mapping was incorrect): 
[org.gss_project.gss.server.domain.Folder#2392]

Normally, you don't need to worry about those. It happens often (especially 
during multiple requests from the webdav client) that two threads try to modify 
the same folder/file. This causes those exceptions. We catch them and retry the 
transaction (Colliding again is of extremely low probability but even then we 
retry again).

Well, I am trying to upload around 20k files total over 200GB using bitkinex 
webdav client and I get lots of http 500/503 errors during uploads and slow 
performance. Thats why I was asking if "org.hibernate" has anything to do with 
that...

Webdav clients tend to flood the server with multiple requests. HTTP 500 is 
returned by the web server (not gss) probably because jboss instance(s) are 
busy.
