CSM VP LEAKING HEAP MEMORY CYCLING KEYS (BASED ON SWITCH FREQUENCY) FOR PERSISTENT CONNECTIONS WHEN USING CSM NETWORK ENCRYPTION
|
| product: |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 |
| Problem 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. |
