Symptoms
  • Output of "top" command shows that FWM process of the MDS is consuming 100% CPU (in "top", press C - the process will appear as "mds fwm").

  • The following errors appear in $MDS_TEMPLATE/log/mds.elg file:
    Fatal error: CPMI Query on table grc_test_elements returned more than 1 object.
    Failed to send reply on session with error code -1 (Communication path is congested)


    Or:
    Fatal error: CPMI Query on table grc_controls returned more than 1 object.
  • Debug of FWM process in the context of MDS (per sk33208) shows the exact same errors.

Cause

Default entries of grc_controls table should not be synchronized.
