I am having the same problem. I have 3 test/development site setup on a serve. They are using ports 1028, 1029 and 1030. Recently, 2 of sites automatically stop and when trying to restart I get the same error.
I have change the ports and then after a day, the same thing happens. I have run netstat -ano and found that "cimlistener" is using those ports.
TCP 127.0.0.1:1028 127.0.0.1:1029 ESTABLISHED 1292
TCP 127.0.0.1:1029 127.0.0.1:1028 ESTABLISHED 1292
I just find it strange that even if I change the ports, they lock up. Any suggestions ?
