Sorry. 2.0.31 with inode patch.

You might be getting hit by the IP fragmentation (so called
"teardrop") bug, upgrade to 2.0.32 to get that fixed or just apply the
following patch which is the bugfix by itself.

Also note that the magic number you forgot it extremely important to
report _always_. We output it for a reason, because with it you can
look up where the kernel has died in your file and let us
know what that location is.
