Event collector-system message server service going to synchronizing state
Recently in one 800xa 5.1 system, the system message server service and event collector service is going to synchronizing state in both AS1 and AS2. After restarting the system message server services all the services become healthy.There is no error in windows application log. the system is running for last three years without any problem.
Can anybody suggest the reason behind this?
Check for traces of exceptions (crash) in C:\ProgramData\ABB\Process Portal A\log\...\...
The exception text/log file carries the same name as the System Message service process name in the Task Manager + a prefix (Exception_Adv...). Look for output with same date & time as the problem.
Contact regional ABB support and make plans to catch a full (binary) crash dump next time it happens. Dump files can be analyzed by R&D.
