Hello, I upgrade a web, squid, mail server (under SMP with 2 pentium III) to 6.1-RC (Apr 9 2006) and encounter 2 `freezing'. The system is still responding to http requests but I can't login on the console or through ssh -- no shell prompt. No more mail delivery. I break to KDB and found more then 1000 sendmail processes waiting for devfs... call boot(0) can't complete the shutdown process. I join the KDB informations. Let me know if more informations are needed.

it happend to me too. power line was down and server was restarted 3 times while FSCK after early unplanned shutdown. i have no time to fix it and fastest way for me was: boot from another source, backup, rebuild array (RAID5 on 3ware 9500S), and reinstall everything :( 2006/4/20, Henri Hennebert <hlh@restart.be>:> > Hello, > > I upgrade a web, squid, mail server (under SMP with 2 pentium III) to > 6.1-RC > (Apr 9 2006) and encounter 2 `freezing'. > > The system is still responding to http requests but I can't login on > the console > or through ssh -- no shell prompt.

If not, could you do so and see if the problem is reproduceable, and if so, whether or not WITNESS (and friends) generate any warnings? It looks like something has leaked a lock, resulting in deadlock. The question is, however, which lock, and where. WITNESS may be able to provide some insight into this; if you could run "show alllocks" with WITNESS in place, that would be helpful also. Robert N M Watson
