Hi everyone,
I have a JEMS installation of Jboss portal, in a cluster with 2 members, in
the last period some nodes of the cluster logs an error due to a lock
timeout.
Is this a configuration problem? Is a known bug?
I think that some portlet spends a lot of time to elaborate data or to load
a content from jackrabbit, until a timeout occurs.
Jboss AS 4.0.5
Jbos portal 2.4
This is the error:
15:20:50,262 ERROR [ContentGetCommand] Cannot get content
