Today, our secondary MX, was hit by a large SPAM storm. The message subject was all the same so I presume a new set of bots was unleashed.<br><br>Anyway, I saw the inbound queue jump up to 1000, and MailScanner stop logging anything too /var/log/maillog. I reloaded MS and it began to process again. After getting through ~ 250 messages it started building up again. I checked running processes and all the MS processes were running, but they all said Checking SPAM lists.
<br><br>My settings are the same on both primary and secondary, the only difference being hardware processing power.<br><br>Primary is a dual Opteron 8GB RAM, children set @ 20 with a 100 message batch size and all okay. Secondary is single P4 with 1GB RAM, children set @ 5 with a 25 message batch size.
<br><br>Has anybody seen this before? We have ordered a matching server to replace the secondary but that is on a two week lead time. Any ideas?<br><br>I will run a strace tomorrow if it happens again to see where it is sticking.
<br><br>Regards,</blockquote><div><br>Haven't seen this particular incarnation, but... What you describe is a bit reminiscent of the old "I've got some non-queue file in the hold queue, and MS just .... hangs...", wouldn't you agree?
<br>So look for anything non-PF-queuefile-like in the hold queue.<br></div><br></div>Cheers<br>-- <br>-- Glenn<br>email: glenn < dot > steen < at > gmail < dot > com<br>work: glenn < dot > steen < at > ap1 < dot > se
