Any indications on > the mysql side? Logs show that this is not a mysql problem. We've got here HA cluster for mysql with Hitachi TagmaStore AMS200 as a storage for them, so there should be no problems with mysql at all in any case. Problems are SA related, looks like a some kind of bug in it, as a simple restart of spamd fixes the things for a while. > P.S. The new qmlog has grep built in. Perhaps I should've made it egrep? Still using older QMTP RPM, and I think that there's no need for qmlog to gain excess functionality. It's against The Unix Way (TM), and it will be always easier for experienced sysadm to pipe to a grep/egrep, instead of trying to remember correct opts for every utility he or she uses. -- Best regards, Alexey Loukianov mailto:[EMAIL PROTECTED] System Engineer, IT Department, Lavtech Corp --------------------------------------------------------------------- QmailToaster hosted by: VR Hosted <http://www.vr.org> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
