Hello friends, I've been detecting that in Task Manager the lsass.exe process starts with 2 MB of memory consumption, and it slowly grows up (i've even see it using 250MB of memory), this makes plesk services fall down. Anybody had the same problem? Any suggestion to fix this memory consumption? The only remedy I have is to restart the server. (There are no viruses or malicious software detected in the server after running several scans). Thanks for your help.
