Running FileMaker 188.8.131.525 on Windows Server 2012 R2. Since yesterday, it happened two times that the Web Publishing Engine stops by itself. I checked the logs and no errors are reported. We have an average of 50 requests per minute. Server have 4 CPUs, the load is ok, RAM (16 Go) is fine too.
What can cause this? We had the same kind of problems with FileMaker 9 on OS X 10.4 (on a poor PowerMac G5).
