I recently had a problem on my workstation. (UP1000, 640MB, 4.5-STABLE, also an NFS server for my various testboxes in my home office). I was doing a local cvs diff on the src/sys tree, as well as building the TGA kernel, and doing a few other things (xemacs, gnome, sawfish, konqueror, 20 or so shells). The cvs diff got wedged in (I think) inode. At this point, I noticed that the FFS node malloc pool seemed to be quite near its limit. I killed the make and tried to recover, but I couldn't seem to get the number of FFS node allocations down & other jobs started to wedge on IO. I was intending to drop into the debugger and get a dump, but the machine locked solid when I tty-switched out of X. I have so far be unable to reproduce the problem. I wonder if these two problems might be related..? Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
