logsurfer kills cyrus
I have an issue where logsurfer regularly kills the master cyrus daemon.. If an event occurs which causes logsurfer to generate a few thousand messages and sends them to my cyrus server, it seems lmtp falls over and never recovers. I have to restart the master daemon each time. I figure if i can DOS myself then someone elso could do it as well.. Are there any tuning / performance / mail bomb protection measures i can look at ? I have set a confMAX_QUEUE_RUN_SIZE = 1000 in sendmail but this does not seem to make any difference.. Sendmail seems to handle the load fine, its just when cyrus tries to deliver the mail that things fall apart. Thanks..
lmtp behaviour
Hi, I'm running cyrus-imapd-2.1.12 with sendmail 8.12.9. I have an issue where lmtpd seems to refuse connections. This behaviour seems to occur when a large volume of mail is delivered to the box. I notice that there is an lmtpd process fo each message that is being delivered so if i send a few hundred emails i get a few hundred ltmpd processes. Is this normal ? I have specified FEATURE(local_lmtp) in sendmail.mc and have the following in my cyrus.conf file. lmtpunix cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0 The error in my maillog is: Apr 5 10:00:55 myserver sm-mta[58837]: h3500t9u058768: SYSERR(root): Could not connect to socket /var/imap/socket/lmtp: Connection refused by localhost Can anyone offer any advice ? Thanks.
