I'm still keeping an eye on the MPT code to see if someone changes something that CAN be affecting my timeout issues/reset, and if I see something promising, I'm willing to dump out the entire server to tapes, and test run (I have sufficient spare tapes to actually test without losing data), but such a job will take me a week to prepare, and another to test. Quite a bit of time for something that "may" solve my problem... ;) //Svein --=20 --------+-------------------+------------------------------- /"\ |Svein Skogen | svein@d80.iso100.no \ / |Solberg =D8stli 9 | PGP Key: 0xE5E76831 X |2020 Skedsmokorset | svein@jernhuset.no / \ |Norway | PGP Key: 0xCE96CE13 | | svein@stillbilde.net ascii | | PGP Key: 0x58CD33B6 ribbon |System Admin | svein-listmail@stillbilde.net Campaign|stillbilde.net | PGP Key: 0x22D494A4 +-------------------+------------------------------- |msn messenger: | Mobile Phone: +47 907 03 575 |svein@jernhuset.no | RIPE handle: SS16503-RIPE --------+-------------------+------------------------------- If you really are in a hurry, mail me at svein-mobile@stillbilde.net This mailbox goes directly to my cellphone and is checked even when I'm not in front of my computer. ------------------------------------------------------------ Picture Gallery: https://gallery.stillbilde.net/v/svein/ ------------------------------------------------------------ --------------enig310F97465502DC5CA5A295AA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxHPzMACgkQODUnwSLUlKRoOQCgtZtLes73SLFze551+Rsc3s3v 1lwAnjXhQE7oCXEatIvI7FHuGSvdJqSI =2dlo -----END PGP SIGNATURE----- --------------enig310F97465502DC5CA5A295AA--
