Error description

• After the installation of maintenance, the Omegamon XE for DB2
  PE on z/OS Server is suffering from repetitive error messages
  msgFPEV1315I, which are filling up the spool and require the
  server to be stopped:
   FPEV1315I  DBS NUMBER OF PARALLEL SESSIONS EXCEEDS SPECIFIED
              MAXIMUM
  On the PE Client, error messages DGOK1446 (server timeout) and
  DGO1421 (maximum number of TCP/IP sessions exceeded) are conti-
  nuously issued.
  Initial analysis has unveiled two problems but more trace points
  have to be added to the code to isolate the root cause:
   1. PE Client suffers from timeouts causing reconnects.
   2. PE Server does not free sessions after they become unused.

  ****************************************************************
  Multiple use of the same pair of host and port during the
  PE Client configuration results in misconfigured communication
  paths between the PE Client and configured collectors. This will
  result in timeout conditions, leave unused sessions open and
  finally exhaust the maximum available sessions.
  

Problem conclusion

• The server will respond to the PE Client request, close the
  communication session and provide the freed session for reuse.
