I did a cvsup and rebuilt world and kernel last night, and I'm about
five hours into an openoffice build with no sign of any problems. I
haven't played with ^Z and fg. Ill try that tonight if the currently
running build is successful.
Another question, is your system UP or SMP? Mine is UP.
Turning on softupdates on your SCSI disk and doing the build there would
be an informative datapoint.
My kernel is compiled with
options DEBUG_VFS_LOCKS
That option has turned up some problems in the nfs client code, but I
haven't encountered any problems in the ufs code.
Here's my system configuration:
