last night usermin behaved very strange on one single user.
When the particular user try to log-in usermin with 2 processes (miniserv.pl) stuck on top with 100% CPU and 30% and rising on each process.
At the same time usermin panel is constantly loading in the browser and showing only one small part of the left menu and nothing more.
When I stop (service usermin stop) usermin it stops and everything went back to normal.
I tried to login with other user and everything was normal without any issues but every time I try to login in this particular user the issue come again.
So the issue is repeatable.
Client said that at that moment he was trying to set email filters.
Uusermin enabled modules:
Filter and Forward Mail Read Mail SpamAssassin Mail Filter
If you need more information I will try to get it.
