Local deliveries are very slow -- I cannot seem to get local concurrency to go to double digits, even if the number of queued messages is high (say 20k). This results in the local queue building up rapidly. All remote deliveries go out to a separate machine listed in smtproutes. qmail has the big-concurrency patch applied. It's mostly set up according to LWQ, except that we also run qmail-qmqpd. Linux has been patched to increase NR_TASKS to 4090. This is for a quad Xeon, 2GB RAM machine. Filesystem is ext2 on RAID5. The permissions on /var/qmail/queue/lock/trigger are as expected, prw--w--w-. I can provide additional info if needed. qmail-showctl output is quite extensive, as we host many virtual domains with vpopmail. Here's output from `vmstat 10`: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 0 3 0 8 3184 1836572 59792 0 0 8 12 15 12 6 3 13 0 9 1 8 3024 1835872 59476 0 0 59 188 640 1617 2 3 95 0 2 0 8 3480 1834692 59708 0 0 38 169 777 1732 3 4 93 2 11 1 8 2740 1832468 59208 0 0 58 184 669 1569 3 4 93 1 2 0 8 6304 1821128 64148 0 0 51 275 674 2171 15 5 80 0 3 0 8 18976 1824612 52284 0 0 61 124 606 1522 14 22 63 0 1 0 8 20396 1824612 53752 0 0 21 297 792 2114 4 4 92 Here's some of my qmail-send logs. I've been watching the logs roll by for the entire day and I don't see anything strange. 210.16.71.8 is our outgoing mail machine. @4000000039b348ff1b00fc9c new msg 521463 @4000000039b348ff1b02f09c info msg 521463: bytes 10113 from <LifeMinders.com@mai lgate.lifeminders.com> qp 2353 uid 502 @4000000039b348ff24f7f37c new msg 521464 @4000000039b348ff24fa29e4 info msg 521464: bytes 8204 from <sentto-1870233-2567- [EMAIL PROTECTED]> qp 2355 uid 502 @4000000039b348ff2eb6465c starting delivery 3020: msg 499042 to local edsamail.c [EMAIL PROTECTED] @4000000039b348ff2eb6b3bc status: local 2/120 remote 31/500 @4000000039b348ff2eb874f4 starting delivery 3021: msg 500497 to remote bluer@gop lay.com @4000000039b348ff2eb8e254 status: local 2/120 remote 32/500 @4000000039b348ff2ebf5e7c delivery 3018: failure: User_is_over_quota_email_retur ned/ @4000000039b348ff2ed5865c status: local 1/120 remote 32/500 @4000000039b348ff2ed795b4 delivery 3019: success: 210.16.71.8_accepted_message./ Remote_host_said:_250_ok_968050802_qp_3363/ @4000000039b348ff2eda1a3c status: local 1/120 remote 31/500 @4000000039b348ff2ef0a7ac new msg 521506 @4000000039b348ff2ef2d25c info msg 521506: bytes 1942 from <Ryan@alittefaqsteel. com> qp 2929 uid 502 Any hints would be appreciated.
