Store is locked... waiting 10 seconds
Hi Everyone
A user is complaining about his application logs being filled up with
"Store is locked... waiting 10 seconds". The KahaPersistenceAdapter
seems to be having trouble obtaining a lock. I am using an embedded
broker, but the broker is only ever started once. I am quite sure of
this. The only other scenario I can think of, aside from a possible bug,
is that the customer shutdown the application uncleanly and a lock file
was left lying around. Has anyone else encountered this situation? Where
else should I be looking to solve this. Any ideas?
Much appreciate
Jamie

What version of ActiveMQ is your user using? If its any later version, i.e. 5.5.0 or higher, I suggest switching to KahaDB as the persistence adapter.
