Hi list- We have been facing with delays in message processing for a couple of days already. It usually takes 7-12 seconds to check the message but now it takes ~30 seconds with some spam messages passing through (scored as SA:0(?/?) which means some checks were timed out).
SA 3.2.3, called by qmail-scanner-st-2.01st [20070204], is running on FreeBSD 6.2-STABLE. Here is my local.cf: required_hits 5.5 skip_rbl_checks 0 dns_available yes add_header all DCC _DCCB_ _DCCR_ Status "_YESNO_, hits=_HITS_ required=_REQD_ tests=_TESTS_ autolearn=_AUTOLEARN_ version=_VERSION_" trusted_networks 192.168.0. lock_method flock use_bayes 1 bayes_path /var/spool/spamd/.spamassassin/bayes bayes_file_mode 0666 bayes_min_ham_num 150 bayes_min_spam_num 150 bayes_auto_expire 0 bayes_auto_learn 1 bayes_auto_learn_threshold_nonspam 1.1 bayes_auto_learn_threshold_spam 8.2 use_auto_whitelist 0 auto_whitelist_path /var/spool/spamd/.spamassassin/whitelist auto_whitelist_file_mode 0666 use_dcc 1 dcc_path /usr/local/bin/dccproc dcc_home /usr/local/dcc dcc_options -x 0 dcc_timeout 10 use_pyzor 1 pyzor_timeout 60 pyzor_options --homedir /usr/local/etc/mail/spamassassin use_razor2 1 razor_timeout 60 razor_config /usr/local/etc/mail/spamassassin/.razor/razor-agent.conf I also use rblsmtpd running checks on sbl-xbl.spamhaus.org, bl.spamcop.net, dul.dnsbl.sorbs.net and t1.dnsbl.net.au. The delay is around 30 seconds for *some* messages. I can't figure out what is causing it. I've faced with such "delayed" messages before but it was 1-2 message per month and spam only. Now it's quite a lot during a day for any messages. At the same time, there are messages being processed fast enough. I tried to disable razor/pyzor/dcc and turn off RBLs - it had no effect. I suspect some DNS checks are timing out but can't find which one. We have plenty of bandwidth available, and as far as I can see no problems with DNS. No errors reported by spamassassin -D --lint. The only error(?) I see comes from dnscache: @4000000046f24dfe37181e4c servfail 33.20.65.165.combined-hib.dnsiplists.completewhois.com. input/output error @4000000046f24dfe3719b874 servfail 45.35.65.165.combined-hib.dnsiplists.completewhois.com. input/output error but I'm not quite sure where this check comes from? Anyone with the similar symptoms? Any advise would be greatly appreciated. Thank you.
