We have 800xA System 6.0.3, severs installed on Windows Server 2016 LTSB Standard. On Information manager server lsass.exe process take a lot of RAM to several GB. After restart it work normally by during the time it increase the occupied RAM. In windows log we see that this process has Audit Failure to ABB PAS System Services.

I've seen this a number of times, 800xA computers dying from excessive memory usage by LSASS.EXE

Unfortunately, I am not aware of any magic cure - you seem on the correct trajectory by studying audit events.

I recommend filing a support case with your regional ABB support center.
