Subject: [uml-devel] SKAS race condition status?
Date: Mon, 17 Oct 2005 17:50:52 -0500	[thread overview]
Message-ID: <43542ACC.7020108@theshore.net> (raw)

Has there been any progress on the race in SKAS?  I've been dealing with 
2-4 hosts crashing a week.  Same thing happens on my old SKAS kernel, 
2.6.7 with skas3-v4 or so.

Code:  Bad EIP value.

Is there code I could add there to OOPs rather than panic?  I'd prefer 
to have just one UML go down rather than the entire host.

Thanks!
