This would be easiest to solve - all other problems are worse. Yes, I'm sure, anyways there is about 40G free space now on that drive and it's not so easy to suddenly fill it up > b) How is your IO rate at the time you run out of space? Nothing ususial, except I just noticed that at any time, not just when the problem arises, the %slo-z value is about 97-99%. May be it has nothing to do with this problem, but on other similar servers it's not that high. > c) Did you try fsck-ing the file system? Last time two weeks ago the server was rebooted ungracefully and fsck'd in foreground (it has background_fsck="NO"). After that, I didn't have a possibility yet to reboot it in single-user. If I could do it remotely it would help but there is no KVM or anything there. Honestly I'm a bit afraid of doing "kill -1 1" or "reboot -qn". > d) Why can't you upgrade to a more recent version of FreeBSD, like 7.1? The server is in production and there is no other server to substitute it during the downtime. ---- Alexander Varshavchick, Metrocom Joint Stock Company Phone: (812)718-3322, 718-3115(fax)
