So I have a question and see that some people have reported this problem with SmarterStats but I haven't seen anything posted about SmarterMail.

 

So today I had an issue with SmarterMail where IIS freezes web sessions out of nowhere. You try to get to the login screen of SmarterMail and it will take forever. The only recourse I have had at this point is to restart the IIS service on the mail server itself and all is fine for a few days. So when this issue cropped back up today I looked at the taskmanager on the mail server to see if IIS crashed or if it was using lots of memory. W3WP.exe was using at the time about 850mb of memory. Which our server has more than enough memory to run any of the mail software we have. Currently we have 16GB installed. So I restarted the service again and all was well. Looking through my error log in SmarterMail I found this entry and it seems to populate around enough times in the log that it looks to be serious:

I took the username out of the log and replaced it with X's.Has anyone else see weirdness like this in their error log? And it might be coincidental, but at the time the IIS service takes a really long time to hand out the login page or slow the interface down if you have it open already is when this error seems to happen.

 

Any input would be greatly appreciated.
