Profiler Server 4.12.1
Initially the agents were also running 4.12.1 on a mix of windows and linux, a few have been upgraded to 4.12.4 during troubleshooting.
The referenced error would appear on the agents after some time and then all the important modules would stop working. The most important to us being the File Analysis module. All of our agents are set up to analyze NAS shares; we are not interested in running FA rules on any local storage of these agents. The windows agents were assigned the CIFS shares and the linux agents were assigned the NFS shares.
I had a ticket open with solarwinds for the problem when it first appeared on the windows agents, and it was resloved by simply allocating more memory to the java process heap max. I tried the same resolution on the linux agents with no success so far.
Has anyone else seen this problem? We have 2 independant networks and the problem appears on both.
