Check sod memory in Chassis

Problem
Management consoles for Chassis and VCMP guests are accessible. All VIPs are marked up but the applications were not loading.

Solution
Execute the command to view sod memory usage

 #top -cbn 1 | egrep 'sod|COMMAND' |grep -v egrep
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 7357 root      20   0  1628  352  328 S  0.0  0.0   0:00.10 runsv sod
14597 root      20   0  988m 988m  22m S  0.0  6.2 372:24.04 /usr/bin/sod

For example, value under RES memory shows 988m. This is too high. Typically, it is expected to be 50m as per F5 support. 

Execute the command to clear out sod memory usage

#tmsh restart sys service sod

# top -cbn 1 | egrep 'sod|COMMAND' |grep -v egrep

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

 7357 root      20   0  1628  364  328 S  0.0  0.0   0:00.11 runsv sod

 8022 root      20   0 30096  28m  22m S  0.0  0.2   0:00.12 /usr/bin/sod

Now the sod shows reduced memory footprint 28m
