BBSM 5.3 SP2, BUG CSCeh32156, reboot

[Volker Janusch]

Hi,

are there any detailed information about BUG CSCeh32156. Our customer updated to SP2 and the release-notes containes small information about this issue.

With SP1 the BBSM 5.3 had the problem: reboot to irregulary moments. May be also caused by too may imported ports (2580) due to import of all ports from some Catalyst 4506. But only a few ports (50 -50) are located to BBSM-INSIDE-VLAN.

Thanks in advance for further informations.

Symptom for this bug:

BBSM sometimes unexpectedly reboots.

If system is not configure to automatic reboot or write debug on system failure:

blue screen/log said D1 stop error and memory dump at AtNat.sys

Conditions:

Rare timing condition together with the release of DHCP (ipconfig /release)

from client.

Workaround:

Increase the driver's DHCPEntryTimeOut will minimize the on set of the timing

condition.

SP2 contains the fix to the ATNAT driver to alleviate the above issue. No more details are available as to the physical fix imposed to the driver itself.
