    Why this question never been answered? lock acquisition

    Michal Glowacki Novice

      hi,

       

         I am browsing the web for solution of (what can I see) common jboss cache 3.x problem of:

       

      org.jboss.cache.lock.TimeoutException: Unable to acquire lock on Fqn [/PageCache/pop_up_76684] after [15000] milliseconds for requestor [Thread[ajp-0.0.0.0-8009-178,5,jboss]]! Lock held by [GlobalTransaction:<null>:32070]

      org.jboss.cache.lock.TimeoutException: Unable to acquire lock on Fqn [/PageCache/pop_up_76684] after [15000] milliseconds for requestor [Thread[ajp-0.0.0.0-8009-178,5,jboss]]! Lock held by [GlobalTransaction:<null>:32070]

        I have seen some questions on the discussion boards, but noone is replied.
        MVCC model description state that read operations does not acquire locks - looks like something else to me. Perhaps it's a problem of eviction config? I did not define any (is there default one?) and number of nodes is around 20k, attributes like 45k. Possible that look up takes more than lock acquisition timeout?
      Regards,
