Smartermail Service keeps Crashing | Stopped Frequently Solution

We PROBLEM:

We are using SM 11.7 Enterprise

Whenever someone makes a change in Plesk CP, when Plesk talks to SM, it's crashing.

When we go to the SM page, it says:

Server Error in '/' Application.

No connection could be made because the target machine actively refused it 127.0.0.1:17001

The service is still running; if we restart the MailService.exe process, it starts working again.

We originally thought this was a Plesk issue and opened up a ticket with Parallels; however, they have said it's an issue with SmarterMail, and I should contact SmarterTools.

As it's a Bank holiday, I thought I would post on the forums to see if anyone else knows the fix to this, as likely no support will be available until next week.

Nothing is in the event viewer about this, ie, a crash log, as the service does not stop to log anything.

SOLUTION

I've contacted the SmarterMail support and solved this issue. Just kill the mailservice.exe process and restart the service. That should solve this issue.
