With my web application, when usage is very heavy (this time of the year), I have been having the publishing engine shut down. When I look at the processes, the fmscwpc process is approx. 3 times larger than it would normally be. I can get it back working, by stopping and restarting the FileMaker Server service. After doing that, the fmscwpc process returns to its normal size., and the users are good to go for an indeterminate amount of time, perhaps a day, or maybe more, before it happens again. I am using FMServer 12 AdvancedV3, and all the clients who are having this problem, are on Windows Server 2008 R2. Client access to the database is all through CWP.
When I look at the logs, I see no indication of why it shuts down. Mostly 401 errors, resulting from a find where no records were found.
I'm at a loss to figure out how to troubleshoot this.
