Jul 22 16:54:26 <myHost> kernel: Out of memory: Kill process 28475 (fglam) score 58 or sacrifice childJul 22 16:54:26 <myHost> kernel: Killed process 28479, UID 5001, (qcn_watchdog) total-vm:18716kB, anon-rss:156kB, file-rss:96kBJul 22 16:54:26 <myHost> kernel: oracle invoked oom-killer: gfp_mask=0x200da, order=0, oom_adj=0, oom_score_adj=0 -
Resolution
A Linux system that runs out of memory kills automatically processes (OOM killer). Here it kills the Foglight Agent Manager (FglAM) process, but that does not mean that the FglAM is the root cause of the issue. It might be the amount of processes with makes the machine to run out of memory.
Please consult your Linux administrators.
