    TimeoutException

    valerio de minico Newbie

      Hi all,

      I use JBoss Cache Pojo Edition v. 3.0 on a JBOSS AS 5.1.0. I have a cluster with two nodes and the following is pojocache configuration file:

       

       

      <?xml version="1.0" encoding="UTF-8"?>

      After about 5-10 minutes and randomly I have this timeout exception:

      It seems that a timeout occurs on a lock acquisition...

      Any idea about the cause???

       

      Thanks,

      Valerio.
