SpamAssassin false positives on DATE_IN_FUTURE_96_Q?
by Gilbert E. Detillieux 23 Feb '16

23 Feb '16

I mentioned this problem at the last round-table session, but didn't get a solution, so I thought I'd post it here, just in case anyone has any suggestions to offer. I'm still seeing a whole bunch of false positives in SpamAssassin, since an update was installed in mid-September on a CentOS 5.7 system, for a rule called DATE_IN_FUTURE_96_Q, which is only supposed to be triggered when the "Date:" header has a date that is 4 days to 4 month ahead of the date in the "Received" header that … [View More]

ZFS I/O strangeness
by Adam Thompson 02 Apr '12

02 Apr '12

I have a ZFS RAIDZ3 filesystem under OpenSolaris (actually a Nexenta build so a GNU userland on top of OpenSolaris kernel). "dd if=filename of=/dev/null bs=8k" gives me ~66Mbytes/sec. "cat filename | dd of=/dev/null bs=8k" gives me ~142Mbytes/sec. WTF? Why would using cat *increase* the overall speed? The only thing I can think of is readahead, but why would cat cause that to happen while dd doesn't? -Adam Thompson athompso(a)athompso.net

Dunno.

NFSv4 locking problem
by Trevor Cordes 30 Mar '12

30 Mar '12

A recent update (kernel, or something else) seems to have messed up file locking over NFSv4 on my system (yes, v4 allows for locking). I use locking in perl scripts over NFS and it's always worked until now. I checked and lockd is running on the server still. A test case is at the bottom of this email. The problem hits on line 13 where the open-for-write happens. It dies with "Input/output error". The client's /v/l/messages says: [156474.509107] nfs4_reclaim_open_state: Lock reclaim … [View More]
