Thank you for your interest in helping out here. So I will start with the easy questions and try to get into the kernel later.
Based on the History I believe that the problem is the client/cache manager. We had this kind of problems before. In the first round the client made the server crash. An upgrade of the client from Ubuntu Karmic to Ubuntu Lucid solved that. Next the server got overloaded so we upgraded from Ubuntu Hardy to Ubuntu Lucid. Threw out some more of the old FreeBSD and stopped running virtual servers in ESX. Some time passed and we got blocking fileservers tuning of the fileservers solved some of the problems. We also threw some "random" options at the client and redesigned the webmail to make users stick to a single IMAP backend. This time around we are rebuilding the IMAP servers for mail clients and since we have a little time before the users arrive with the pitch forks I am trying to understand what the "right" settings should be. In the earlier cases the server would stop serving any clients so unrelated services (like webservers) would stop and the users would complain about not beeing able to save their files. This time it is only the single client/cachemanager that is affected. The server is running Ubuntu Lucid Lynx with the included OpenAFS 1.4.12+dfsg-3 package. Fileserver is started with "-L -abortthreshold 1024 -syslog" The client is running Ubuntu Lucid Lynx with the included OpenAFS 1.4.12+dfsg-3 package. The "random" options on the webmail backends are "-stat 15000 -dcache 6000 -daemons 6 -volumes 256 -rxpck 2000 -files 50000 -afsdb -dynroot -fakestat" the once I am testing now are "-daemons 6 -afsdb -dynroot -fakestat". To the best of my knowledge there never was a problem running rxdebug <client> 7001. I know for a fact the rxdebug <server> 700X works without problem during the hangs.
