	Hello

After some troubles with lockmgr that seem to be fixed after 
upgrading to 3.1-stable-990311 with a 15 days uptime, I fetched 
yesterday 3.1-stable and rebooted on a new kernel (with maxusers==512).

(I changed stable versions because I got "Out of mbuf clusters - adjust 
NMBCLUSTERS or increase maxusers!" crashes and I thought that was the 
opportunity to give stable-990328 a chance to run.)


During the night my bi-pentium II (with 512 Mo of ram) crashed with the 
following ddb trace :

panic: pipeinit: cannot allocate pipe -- out of kvm -- code = 3
mp_lock = 01000001; cpuid = 1; lapic.id = 00000000

If someone has an idea of what to do...



Thanks in advance.

Best regards.
