[OpenAFS] HELP! We 've lost our sync site

[Mosley, Mike]

I have not seen the notes about the Ubik time overflow problem.  I'm
currently runnint 1.2.10 under Solaris 9.  I can drop back to 1.2.8.  Is
there anyway I can correct the problem for the short term to correct the
problem while I prepare to back down to the earlier version?

Thanks,

Mike

Did you see the four notes on "Ubik time overflow at 0x40000000"
That is the problem. 

What version of AFS are you running and on wht OS?
If you can't build it yourself, or can't want for the OPenAFS peple
to build a release, maybe some else might have built it by now.
(I have OpenAFS-1.2.10 running on sunx4_58 for the last 15 minutes.)
