I did my best to recreate the heavy I/O conditions that existed when it died there before, with Evolution being opened just as cvs starts the first writes. I opened Transmission-gtk with a few LiveDVD ISOs just for good measure. The system was loaded enough for "su -" to stall for 20 seconds at some points but ext4 survived now. I do believe you have found the culprit, many thanks :) Regards, --=20 Tony Vroon UNIX systems administrator London Internet Exchange Ltd, Trinity Court, Trinity Street, Peterborough, PE1 1DA Registered in England number 3137929 E-Mail: tony@linx.net --=-KzD+RMcyujP4saWCmT7d Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (GNU/Linux) iEYEABECAAYFAkzXLe8ACgkQp5vW4rUFj5rg5QCfbPZRL9u/k92Ury0JkB4I447s yOoAnRA4DJz7HbjHHmznckbmu1rkSSTS =SR2l -----END PGP SIGNATURE----- --=-KzD+RMcyujP4saWCmT7d--
