Mario, it seems your PIX is hitting bug ID: CSCec19113 , if you have access to bug tools take a look at it, bug was reported in code 6.3(2), your code is 6.3(1) so most likely your code has this bug even if it was first reported in 6.3(2) first. See if the work around resolves your issue, if not then I would suggest to plan upgrading to the latest code in the 6.x train which is 6.3(5) as the most stable code in 6.x.

PIX crash in thread PIX Garbage Collector in pix_gc

Symptom:

PIX reloads in PIX during garbage collection

Conditions:

When H323 fixup is enabled.

Workaround:

Disable the H323 fixup.

Further Problem Description:

During processing H225 message, it's possible that the

process might be suspended because of printing syslog

messages, and while suspending, the h225 connection that

is associated to the H225 message has timed out causing

the H225 internal data structure to be chunk-freed. Then

the process resums and at the end of the H225 processing

the H225 internal data structure is chunk-freed again.

Having a chunk freed twice causes the chunk to be allocated

and enqueue to the Garbage Collector queue twice at later

time, which in turn, causes corruption in the Garbage Collector

queue resulting in crash.
