So there's no trend in the last, say, 5 users/IPs to log on before the hang? If you can't find a trend on the user end, you need to do some baselining over time. To see whether POP3 login times get longer and longer throughout the day on an empty dummy account, which would show a chronic memory leak, rather than an acute event. You could do this using just about any POP3 component--the important thing is to time it. You should also set counters on POP3D memory and processor usage to see what its peak non-fatal usage is. >> - What happens when you Telnet on 110 during these situations and >> attempt a manual session? > No, I haven't, but I will the next time it hangs and let you know. Yes, do. And you should create a dummy domain that runs off the Registry to see if it also does not accept logins at that time (it may not accept logins for other reasons as well, but you could get a strong negative if it still processes). >> - Is POP3 becoming unbound from the IP altogether? > Sorry, I don't get that, how do I know?

I strongly recommend setting up a couple of dummies, one Registry, one alternate ODBC--Access, normally the worst, will even do for this testing. (I'm surprised Ipswitch didn't recommend this, even as a deflection.) -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
