Crash-report; 2.2.19pre14-ext3-0.0.6b



Our main NFS-server, running Debian Potato, died this morning whilst
under quite heavy load - due to a runaway perl-script forking of some
200 instances of "/bin/cp" (the load was ~ 50). The server is running
2.2.19pre14 with ext3-0.0.6b. The server is running kernel-nfs.

Assertion failure in journal_dirty_metadata() at transaction.c line 796: "bh->b_next_transaction == transaction"
