Subject: Bug Report - crash copying in large file
Date: Thu, 5 Jun 2008 14:15:16 +1000 [thread overview]
Message-ID: <20080605041516.GA11964@brong.net> (raw)
Hi, random crash dump if you're interested:
Latest stable btrfs (557:4b7e2b315a32)
Latest stable progs (234:e6d157c83cfe)
Latest Ubuntu Hardy kernel (2.6.24-28-generic).
Ubuntu Hardy toolchain (gcc: 4.2.3-2ubuntu7)
Filesystem was freshly rebuilt about an hour ago. I rsynced
over my Maildir and associated offlineimap and mutt
configurations, had offlineimap syncing mail, mutt reading it
and an ~700Mb file being copied in from an NFS mount.
Space - there was about 1.5Gb free when I started the copy.
Still, I'm guessing from the dump it may be a disk space issue.
dmesg says:
