[OpenAFS-devel] Possible 1.3.85 fileserver/volserver problem

[Robert Banz]

Hi,

I upgraded two (pretty busy) fileservers from 1.3.84 to 1.3.85 last 
Sunday.  Everthing seemed to be working right, however, last night both 
of them got into the meltdown syndrome where they 'busy' all requests 
causing much badness to clients that were using them.

The platform is Solaris 10 amd64, up to current patch.

Unfortunatly, I can't provide much debugging information on this -- it 
happened at 2am, so I wasn't quite in the mental state for "collecting 
information".  No out-of-the ordinary messages were in the fileserver or 
volserver logs; the only 'out of the ordinary' event that was occuring 
at the time is that it was well in the middle of our backup window. 
 From what i could tell, .backup snapshot creation had finished about 20 
minutes before things started to go bad, and it looks like 
dumping-to-tape had begun.  Could there be any open fileserver/volserver 
IPC issues?
