SUMMARY OF INCIDENTS FIXED BY THE PATCH

Patch ID: 5.1.114.100
* 3333297 (3333290) In a rare case, LLT may panic in the unload path on AIX


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 5.1.114.100

* 3333297 (Tracking ID: 3333290)

SYMPTOM:
In a rare case, LLT may panic in the unload path on AIX.

DESCRIPTION:
LLT  uses the  xmfree() function of the AIX operating system to free network messages.  This 
function takes a  heap as an argument. This heap is created before allocating memory in AIX.  In  
rare cases, during LLT unload, it may happen that LLT destroys this heap while LLT frees   
messages using the xmfree() function. This causes LLT to panic the box.

RESOLUTION:
Symantec has changed the code to prevent the race case to fix the panic.
