A side note: this is unconfirmed so far, but it seems we had a CDOT cluster decommissioned without first removing it from OCUM/WFA. We are theorizing that this may have caused this memory issue. Hopefully the proposed heap size increase will still help in the future.
What files did you find the -Xmx1536m setting? Both the standalone.conf and standalone.conf.bat files in C:\Program Files\NetApp\WFA\jboss\bin\ showed me -Xmx512M as I mentioned above. This most likely means I modified the wrong files, can you confirm?
1. Is your WFA on windows or linux?
2. What is the problem in WFA you are fcaing. The log messages are fine, but is there some workflow or some failure that you are seeing in WFA?
The log message of java.lang.OutOfMemoryError are fine? We were experiencing REST timeout issues when running workflows and filters. Our ops guys would restart the WFA service, but a few hours later it would stop responding again. That's when I was engaged, and I found the heap space error.
3. Have you got the recommended space and memory requirements on your WFA windows box?
We have not officially asked for space/memory requirements from NetApp support, but we do have an inhouse TAM who I would guess have sized the Windows VM appropriately. The VM is sized as 4 vCPU + 10 GByte memory.
FWIW, I often see SQLWarning messages in our remote syslog collector coming from the WFA4 instance. I will escalate those separately.
The log message of java.lang.OutOfMemoryError are fine?
What I meant was, we got to understand about the error in logs but wanted to know what is really affecting your WFA experience. You have provided that info. Thanks.
I suggest you open a Technical support case to debug this further on reasons why this is happening. This could be an important issue. I can tell you how to increase the Heap memory, but I'm not aware of what unwanted consequesnces it can bring ( if at all ).
So to be safe, file a Technical support case.
