FWSM - recurring error from standby module

Hi. Hopefully this problem will sound familiar to somebody here.

First off, I have a pair of FWSMs configured for active/standby in a 6509 chassis. The FWSMs are running 3.1(1) and my redundant SUP720's are runnning IOS 12.2(18)SXF3.

Exactly every 5 minutes, I receive the following error from the standby module in one of my 7 contexts:

FWSM-3-210007: LU allocate xlate failed

This error suggests that I am running out of memory and need to clear my translations. However, that context typically has only 30-50 active xlates and uses less than 1% of the available memory.

Here is my show failover output:

Note the receive errors. I ', not sure how to interpret those, since the interfaces are virtual and vlan97 is dedicated to the firewalls with no other member interfaces. You may also notice that I'm running on the standby module currently. I forced a failover last month to see if the error would go away and if it would cause connections to drop. Failover worked perfectly, but the error has persisted.

I'd appreciate any suggestions about what to check next.

Thanks!

Re: FWSM - recurring error from standby module

Mike,

Not sure, but what does your show xlate look like on the FWSM receiving the errors? Also, what do your timeouts look like?

I would guess bug unless the xlates just aren't timing out.

Try doing a show xlate deb and see if you notice anything abnormal.

Re: FWSM - recurring error from standby module

Jason,

Thanks for the suggestion. The show xlate debug output looks normal. Timeout on xlates is set to 3:00:00.

A bug sounds likely to me as well. Fortunately, this error doesn't seems to be causing any problems to our users.

Thanks again,

Check out

CSCsb98925 Bug Details

ymptom:

Logging on standby pix is showing message:

%PIX-3-210007: LU allocate xlate failed

When you enable debugs debug process pix and

debug fover fail when a connection is

established the output will look similar to:

Failed to rep un_xlate for np/port/id/0/-1 / -

np/port/id/2/-1 flg: 1000 2000002

Conditions:

Cisco PIX running release 7.0.1. Two PIX devices are connected with a

failover cable and configuration contains overlapping nat(0) and static

commands like:

nat(0) access-list

static (High-sec-interface, Low-sec-interface)

netmask

Workaround:

Remove The overlapping NAT 0 ACL and static configuration.

Addinitonl comments:

Note: the fix for this problem is to warn user of the overlapping NAT 0 and static

config, so they can fix the config. If the config is not fixed, then the same LU

replication error will continue to appear on the standby unit.

Re: FWSM - recurring error from standby module

Your idea looked promising, so I dug into it for a few days. I turned out the customer did have a couple of overlapping NAT and static statements. But after cleaning those up the error persisted, and debug output never showed an error similar to above.

Upon further inspection, we finally discovered a trigger for this event. A Sun Ultra 5 running Cricket(RRDTool) was polling some external switches using SNMP at 5 minute intervals. The xlate error was occurring immediately after the first connection was built when polling began.

After some sniffing to see what Cricket was doing to confuse the firewall, we discovered an internal device being polled on a higher level security interface. It turns out that NAT was set up backwards for this device (the Ultra 5 had a static into the more secure network). The customer removed the static, stopped polling that device, and cleared the xlates on the standby.

The error ceased.

Thank you for the suggestion, Jason! It got us looking in the right direction.
