After upgrading to Satellite 5.6, postmaster process uses 100% of CPU due to taskomatic errata processing

Solution Verified - Updated -

Issue

  • after the upgrade the system has been under heavy load and often unresponsive to basic system requests (ssh login, sudo, ls, less)
  • postmaster (PostgreSQL) process utilizes 100% of CPU:
PID  USER      PR  NI  VIRT  RES  SHR  S %CPU   %MEM    TIME+   COMMAND
9745 postgres  25   0  580m  233m 188m R 100.0  0.7     1342:21 postmaster  
  • If we turn off the taskomatic service, then the PostgreSQL CPU usage and Satellite performance returns to normal. However doing so means errata processing/patching cannot occur, so this isn't a desirable solution.

Environment

  • Red Hat Satellite 5.6 (upgraded from 5.5)
  • embedded Postgres database
