I guess I'll come across as a total newbie for asking this, but I get the above message right after starting an ssh session. The reason I opened the ssh session was that I came across a 500 internal server error on the plesk panel.I tried to look around for similar problems, but all answers I find seem very specific toward variations on this problem. I guess it is a very generic message, if I should provide more info, please let me know what to run.free -m             total       used       free     shared    buffers     cachedMem:          5020        202       4817          0          0          0-/+ buffers/cache:        202       4817Swap:            0          0          0ulimit -acore file size          (blocks, -c) 0data seg size           (kbytes, -d) unlimitedfile size               (blocks, -f) unlimitedpending signals                 (-i) 16375max locked memory       (kbytes, -l) 32max memory size         (kbytes, -m) unlimitedopen files                      (-n) 1024pipe size            (512 bytes, -p) 8POSIX message queues     (bytes, -q) 819200stack size              (kbytes, -s) 10240cpu time               (seconds, -t) unlimitedmax user processes              (-u) 16375virtual memory          (kbytes, -v) unlimitedfile locks                      (-x) unlimitedcat /proc/user_beancountersVersion: 2.5       uid  resource           held    maxheld    barrier      limit    failcnt  1231234:  kmemsize        6061008    6064704   17024866   19647330          0            lockedpages           0          0       3800       4096          0            privvmpages      138119     138227     138256     202568     755228            shmpages          60296      60296     131072     131072          0            dummy                 0          0 2147483647 2147483647          0            numproc              64         64        232        232          0            physpages         30682      30671          0 2147483647          0            vmguarpages           0          0      66400 2147483647          0            oomguarpages      50128      50117 2147483647 2147483647          0            numtcpsock           28         28        500        500          0            numflock             14         14        200        232          0            numpty                1          1         64         64          0            numsiginfo            0          0        512        512          0            tcpsndbuf        275520     275520    4683256    6102456          0            tcprcvbuf        458752     458752    4683256    6102456          0            othersockbuf      48576      49280    1503232    4063232          0            dgramrcvbuf           0          0     240000     262144          0            numothersock         38         38        382        382          1            dcachesize       773048     774892    2194304    2317184          0            numfile            2874       2874       5432       5432       6308            dummy                 0          0          0          0          0            dummy                 0          0          0          0          0            dummy                 0          0          0          0          0            numiptent            64         64        128        128          0
