Upgraded a large e-mail server from 4.7 to 5.3 late December/2004 The 5.3 system never stayed up for more than 3 days (kernel panics - often while running "vacation"). A fair bit of fiddling trying to keep it running for about a month, then gave up. Kept the kernel tree updated, no difference. Reverted to 4.11 about 3 weeks ago, no problems since. Also upgraded a web server to 5.3 during that time, and had to retreat also, same reasons. We do have a heavily loaded 5.2.1 system running well. Main difference between the crashy and reliable system is nfs home dirs on the mail and web servers. nfs server is 4.7 Same hardware in all cases, dual xeon supermicro. At a later time we will invest further diagnostic effort. Sorry for the lack of specifics. -- Bruce Campbell Manager, Science Computing CPH-2374B University of Waterloo (519)888-4567 ext 6991 ---------------------------------------- This mail sent through www.mywaterloo.ca
