Hi guys,
I'm an infrastructure support guy and I was asked to take a look into a possible memory leak in Dynamics AX 2012 application servers. We have 4 environments and 4 app servers. The developers reported that sometimes the servers become so frozen that they had to restart either the Dynamics service or the server itself. They reported cases where AX32Serv.exe used up all RAM on the server. I haven't seen that, but from what I can see now, the process peaks at 5 GB on servers with 8 GB RAM and at 3 GB on servers with 4 GB RAM. However, I cannot tell now how it came down, that is, did the developers intervene or it came down by itself. I would open a support case with Microsoft to investigate this, but first I would like to confirm that there is a memory leak and that AX32Serv.exe has been behaving abnormally.
These servers are running on Windows 2008 R2 SP1 fully patched with McAfee file level AV client.
Another interesting thing I found on one of these servers was LSASS.exe utilizing 3 GB of RAM (out of 8 GB total) and not giving it back at all. However, I'm not sure if this is in anyway related to Dynamics AX.
Any advice would be highly appreciated.
Thanks
Zoran
