I was using some Debian patched 2.6.16 kernel and reiser4-2.6.16-1 patch
for that and suddenly got the error messages attached. The java program
in those error messages is doing a huge amount of writes all the time
and probably in many threads at the same time.

After that I upgraded to Debian patched kernel 2.6.16-14 and to reiser4
patch 2.6.16-4 for that kernel and ran fsck.reiser4. Then I got errors
like this in kern.log after a while:
WARNING: Error for inode 1731981 (-2)
reiser4[nfsd(3817)]: key_warning
(fs/reiser4/plugin/file_plugin_common.c:513)[nikita-717]:

(fs/reiser4/plugin/file_plugin_common.c:513)[nikita-717]:
The nfsd in question was trying to read the file system and didn't
succeed in that. It showed file names but no other information for them.
I have ran fsck.reiser4 again but haven't done any heavy writing on
that file system for now.
The version of fsck.reiser4 and other reiser4progs is 1.0.5-1 (the
version in Debian testing).
