Anybody else having problems with Cyren? Symptoms:

1. Spool fills up

2. Errors in delivery log:

09:16:53 Cyren ran into an error scanning a message.
09:16:53 Restarting Cyren. Too many errors have occured so far.
09:16:53 [29090] Unable to run Commtouch check: Exception while processing message: 29090, Exception: Object reference not set to an instance of an object.

 

We're seeing this on our SM 15.x servers. Disabling Cyren gets delivery going again.
