I have the following error when reading data:

2005-08-26 13:01:25,316 ERROR [.jboss.cache.lock.IdentityLock] (t:32745911 u:2629 s:subscriber b:jbroker) read lock for /sub
scriber/user/2629 could not be acquired by <10.0.20.91:34420>:48 after 15000 ms. Locks: Read lock owners: []
Write lock owner: <10.0.20.91:34420>:43
, lock info: write owner=<10.0.20.91:34420>:43 (activeReaders=0, activeWriter=Thread[tcpConnection-6802-1,5,tcp-server], wait
ingReaders=0, waitingWriters=0, waitingUpgrader=0)

Is data locked by replication thread? How can I avoid it? I should have garanteed replication, so I use synchronous mode.

Regards,
Eugene
