I have this problem with kernels built from sources dated 1996-01-31 and 1996-02-05. A kernel dated 1996-01-08 is ok, but that's kinda old. The system seems quite ok, and responsive, but the compiler or make is spinning wheels madly racking up lots of CPU but getting absolutely nowhere. I tried connecting to a spinning cc with gdb and trying to single step with 'stepi' but it didn't complete, for whatever that is worth. The machine is a 386SX16 with 4MB ram 10MB swap + 3.5MB vnconfig swap using NFS heavily. Memory is short and paging is rampant. I'm planning to compile in KTRACE and DDB to try to track this sucker. Stephen. PS. For the first time ever I have noticed these nonzero entries from vmstat -s: 2 vnode pager pageouts 2 vnode pager pages paged out PPS. It seems infectious, as cron and syslogd seem to be spinning madly now.
