I've been getting a lot of crashes on my remote dedicated server - after they occur (in all sorts of different processes) the server becomes unresponsive and I have to reboot it. They all look something like this:
Feb 18 08:23:37 plex kernel: [1070520.320473] postgres D 00004b40 0 1381 1332 0x00000000 Feb 18 08:23:37 plex kernel: [1070520.320500] Call Trace: Feb 18 08:23:37 plex kernel: [1070520.320509] [<c0271951>] ? ext3_do_update_inode+0x1f1/0x360 Feb 18 08:23:37 plex kernel: [1070520.320515] [<c04dbb5b>] lock_sock_nested+0x6b/0xa0 Feb 18 08:23:37 plex kernel: [1070520.320520] [<c016fc70>] ? autoremove_wake_function+0x0/0x50 Feb 18 08:23:37 plex kernel: [1070520.320525] [<c04e33bd>] skb_free_datagram_locked+0x1d/0x40
Because they all seem to involve ext3 inode update functions I've been trying to run fsck. I sudo touch /forcefsck but after the reboot the /var/log/fsck folder still only contains logs that are months old. I suspect something had changed about fsck in recent Ubuntus but I can't find any documentation.
