On this system, Debian's aptitude binary is started hourly from cron to check for new packages (including virus scan definition packages, this is actually the reason for the update running so often). After updating to 2.6.19, Debian's apt control file /var/cache/apt/pkgcache.bin corrupts pretty frequently - like in under six hours. In that situation, "aptitude update" segfaults. When I delete the file and have apt recreate it, things are fine again for a few hours before the file is broken again and the segfault start over. In all cases, umounting the file system and doing an fsck does not show issues with the file system. I went back to 2.6.18.3 to debug this, and the system ran for three days without problems and without corrupting /var/cache/apt/pkgcache.bin. After booting 2.6.19 again, it took three hours for the file corruption to show again. I do not have an idea what could cause this other than the 2.6.19 kernel. The file system in question is an ext3fs on an LVM LV, which is member of a VG that only has a single PV, which in turn is on a primary partition of the first IDE hard disk, hda. The IDE interface is a VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06). The box is a rented server in a colocation, and I do not have access to the console or physical access to the box itself. I'll happily deliver information that might be needed to nail down this issue. Can anybody give advice about how to solve this?
