Severity: 3-Major


The postgres service gets stuck trying to restart due to child processes from a previous instance not terminating.


The postgres service will not start for some time, often up to an hour. During this period other critical services also cannot start or cannot operate correctly.


This is most often seen on first boot into an upgraded BIG-IQ 7000 system. Other rare cases might also exist.


Find the remaining child processes with this command: # pgrep -a -u postgres Kill these processes with the "kill" command. Typically the only processes that need to be killed are listed with "autovacuum" in the process title, so start with those.
