I suspect that 027_stream_regress.pl hits this kernel bug with high probability[1]. I wonder if the owner of kittiwake and tadarida would consider setting up an xfs file system? Or alternatively, since ext4 didn't support concurrent writes until recently, I wonder if there is an option somewhere to turn the new concurrency stuff off, or failing that, if we could temporarily downgrade the kernel to an older version that does inode-level read/write locking.
