IT32427: CSM VP LEAKING HEAP MEMORY CYCLING KEYS (BASED ON SWITCH FREQUENCY) FOR PERSISTENT CONNECTIONS WHEN USING CSM NETWORK ENCRYPTION

APAR status

• Closed as program error.

Error description

• When using ENCCSM configured network connections, the
  connection will have to change it's key for the connection
  periodically.  The default interval to do that is every 60
  minutes.  It can be configured to do it more or less frequent
  using the switch option in the $INFORMIXDIR/etc/concsm.cfg file.
  For each connection to the server that keeps a connection open
  long enough that this key switch has to happen, the csm vp will
  leak private heap memory when the key switch happens.  Once the
  csm vp can't allocate any more heap memory, you could see
  crashes
  of the csm vp, or you could see client connections (existing and
  new) start to fail with various encryption failure messages.
