Signal 11 caught in process/fiber when doing packet capture on ASA

On an ASA 5505 I receive the following syslog ID 199010, severity = 1:

When doing any packet capture in the ASDM wizard.

Signal 11 caught in process/fiber (Unicorn Admin Handler)/(NULL) at address 0x8a7aaf6d, corrective action at 0x0

The error appears in the log after

'capture asdm_cap_inside interface inside'

Problem occurs on ASA 8.2(1) , ASDM 6.2(1). Despite the error, nothing "bad" appears to happen on the device other than the message being displayed

My questions would be:

1) has anyone else received this error?

2) should i be worried?

3) is this a hardware issue where the device could be failing or is it is more likely a software bug?

Re: Signal 11 caught in process/fiber when doing packet capture

We are hiting an internal bug. Either we have to wait for next interim release in which it would be resolved is 8.1(1.104).

The workaround would be to take the captures from the command line interface or dowgrade the ASA to 8.0(4.6) or greater then .6. I would suggest to upgrade it to .25
