[Info-vax] BIND server processes failing: %SYSTEM-F-OPCCUS

[Steven Schweda]

   More fun.  While waiting for the next Apache problem occurrence, I
happened to notice multiples of this:

%%%%%%%%%%%  OPCOM  28-DEC-2021 09:29:25.85  %%%%%%%%%%%

   Log file (SYS$SPECIFIC:[TCPIP$BIND]TCPIP$BIND_RUN.LOG) ends so:

   It's up to TCPIP$BIND_61 after about six days.

   Without knowing what's happening around MEM.C;1:639, I don't know
what to investigate.  User/process quotas?  DoS attack? ...?
