OpenJDK high CPU usage

Ron Cates
in FileMaker Server 19

Featured Replies

I have a FileMaker 19.2.1.23 server installation on a windows server 2019 AWS r5.2xlarge ( 8 vCPUs, 64 Gigs RAM )

recently moved from an in house server with 6 core 64 Gigs RAM

Today after some performance complaints I noticed the CPU usage was much higher than it had been on the inhouse server. I have 10 to 15 users accessing via webdirect and what I noticed is that more than half the CPU usage is the OpenJDK Platform binary. It's consistently running higher than anything else on the server.

Is this to be expected or should I suspect that something is wrong?

In my test environment, and on another AWS deployment with just a couple users my observation is that the OpenJDK runs at a consistently lower percentage than the web publishing engine. But on the problem server it is running at a consistently and significantly higher percentage than the web publishing engine. Is that an indication of something? If so, what should I be looking for?

Just got to the end of the day and was able to get everyone out of FileMaker and shutdown the FileMaker server and OpenJDK is still bouncing around at 20 to 30 percent CPU usage.

Anyone have any idea what else could be using OpenJDK? The server is dedicated for FileMaker server so there is nothing else running on it.
