Symptoms

The SQL*Net Listener process dies and needs to be restarted.

The Alert log may contain additional information that suggests problems with OpenVMS processes.

For example:

      skgpspawn failed:category = 27142, depinfo = 924, op = skgpspawn_error, loc = skgpspawn3 

      ksbsrv: No startup acknowledgement from forked process after 30 seconds

The first error shows a 'depinfo' value of 924.

This translates to the following OpenVMS error ($ exit 924):

      %SYSTEM-F-NOSLOT, no PCB available

The OpenVMS help for this error is :

     The maximum number of processes that can be created at one 
     time has been exceeded.

The second error suggests that we (Oracle) have requested that a new process to be started and,
after waiting for 30 seconds, find the process has not been successfully started.
