Solaris 10, ufs filesystem (wrapped by lofs, mounted from a SAN), Fedora
3.2.1, Java 1.6.0_13.

Yes, as a matter of fact, now that I look, there are:

This purge occurred as part of a batch purging process, in which some
30,000 objects were being sequentially purged. All the other objects
were purged successfully.
The first purge that provoked the error (which occurred a few months
ago) was a one-off, however.
