This is a follow on to this issue, we are deploying as a servlet using
WO 5.4.3 we modified our Database Context Delegate so it now extends
ERXDatabaseContextDelegate, we are initializing the remote
synchronizer manually by calling:
ERXObjectStoreCoordinatorSynchronizer
.synchronizer().initializeRemoteSynchronizer();
this is happening very early on in our application.java right after we
receive "ModelAddedNotification", everything seems to behave as it
should e.g. cached objects are being refreshed on different instances
except we are getting the following exception on a frequent basis:
[Thread-2] DEBUG NSLog - *** EODatabaseContext: access without lock
Our application is usually deployed in a multi-server, multi-instance
environment we just want to make sure this is not going to create any
locking issues... any help is greatly appreciated ...
Thanks,
Saad

I did a thread dump to see what was executing when this was
occurring – it looks like the problem is in the
ERXObjectStoreCoordinatorSynchronizer.

Any thoughts on this? I am a little nervous about adding lock()
statements into the Wonder code.
Thanks in advance for any feedback.
