Hi all, I have a Cisco Unity 4.0(3) SR1 server in vm only setup with Win2k and Exchange 2k on box. It has been working fine for a few years but after the system has been running for a couple of days there is no access to the system administration tool and Unity is reported as not running in the system tray icon. It appears to be related to a problem with the avcsgateway process as it starts to consume large amount of memory (over 650MB) and if I restart the avcsgateway service it then works ok again (for a day or 2 at least). Does anyone have any idea what may be causing this? Thanks for any help.
