Yes, there's a lot of chatter. Disable the Kaspersky scan engine. _____ From: Tom Kern [mailto:tpkern@xxxxxxxxx] Sent: Thursday, February 16, 2006 4:48 PM To: [ExchangeList] Subject: [exchangelist] Sybari antigen Has anyone had any issues with Sybari Antigen for Exchange 7.5? I have 2 bridgehead servers that have "Messages awaiting directory lookup" queue constantly building up. My GC's are fine with no errors. I do have less than the 4:1 ratio MS recommends(more like 8:1). However I've never had issues. The app logs on the bridgeheads log nothing even with diag logging turned up. A reboot doesn't help either. The only thing that helped was disabling Antigen(and no, I don't scan the M: drive, or log files or inetpub,etc). Was wondering if anyone else knew of an issue with Sybari and Exchange 2k post sp3 rollup. Thanks alot
