This sounds familier to the lockup I was having when a user with a huge mail spool read mail. See "2 lockups in 24 hours" message. I didn't bother to post about the 3 more within the following 24 hours. I've been running for a day and a half after applying the later patch in PR kern/8416. I am using imap-uw for mail spool access. This was a new problem after an installworld on or about 5/1, but mail spool file sizes here vary quite widely so that could also be a factor. I'm still keeping my fingers crossed. Cliff On Tue, 4 May 1999 lambert@warped.cswnet.com wrote: > Hi guys, > > I've run into something I don't understand.
