I noticed in my checks this morning that one of our process engines restarted it self last night. In the bg-ca.log file I see this:
WARN 2015-11-01 21:17:00,646 [Config Monitor] config.TenantConfigurationManager (none:none:none:none) Found invalid database connection for local tenant clarity
Then the PE restarts itself.
I have been trying to determine the cause of the db connection issue. On the db server I can't see anything in the Event Logs which would suggest that it was the cause. I was looking for possible network issues or errors relating to the SQL Server service but couldn't see any.
On the server where the PE is running, I also checked the Event Logs.
I see this warning: "TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint."
I'm not sure if this warning would have led to the disruption in communication between the app server and the db though?
Could anyone suggest anywhere else I can look to try to determine the case? Thanks!
