118855-36 and openafs 1.4.10 is where I started to see issues.  
However, a coworker was also screwing around on the systems and  
another was remotely putting them to sleep.

I also saw issues on Solaris 8/sparc with 1.4.12 and ended up  
reverting to 1.4.8 which was the previous stable and I didn't see  
these issues.

I was seeing a variety of other issues, where the afs access wasn't  
locking up, but inetd was locked up like it was attacked (and it may  
have been), however this happened on solaris containers, and it only  
affected the single container instance not the host where the client  
actually lives.

Off the top of my head, some of the kernel changes affected the  
security policy (unable to even disable it), the name services  
(dns/username lookups) and the built-in kerberos mechanism.

Im actually kind of wondering if there is a memory leak in there somewhere.
