Error at end of hashing

[artifex@freemail.hu]

I got the following error at end of hashing: rtorrent: DownloadList::confirm_finished(...) download->resume_flags() != ~uint32_t().d

I am using r1020 on FreeBSD 6.2. I downgrade to r1016 because r1022 looks as an in progress version.

I get the same error using Gentoo ebuilds (rTorrent 0.7.8/0.11.9);

rtorrent: DownloadList::confirm_finished(...) download->resume_flags() != ~uint32_t().

This appeared at 100% of hashing a 7945MB file. Download target is ReiserFS on LVM.

Could this be because of swapping/memory issues? - because I observe rather frequent kernel (2.6.23, not genkernel) errors in the syslog while hammering my server with rtorrent. I've read about the kernel error other places in this forum, but I never found a good explanation why it occurs. Example of error:

I get this too. The only thing in my logs however is the following:
