X-Mailer: VM 6.75 under 21.1 (patch 12) "Channel Islands" XEmacs Lucid Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG How & how often do FFS nodes get free'd? I recently had a lockup on my workstation. (alpha 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 a 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 attmpted to vty-switch out of X. I've so far been unable to reproduce the problem. BTW - since this happened, I've been paying close attention to what vmstat says about FFS node usage: % vmstat -m | grep FFS 512 ATA generic, UFS dirhash, FFS node, newblk, NFSV3 srvdesc, FFS node 23670 11835K 11861K 79618K 336089 0 0 512 Is this normal?
