Why this question never been answered? lock acquisition

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]

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,

Michal

is this thrown on a read operation? Can you provide the entire stack trace?
I kindly suggest using infinsipan for this - this is the jbosscache 4.0 (and much more).
Cheers,
Mircea
