I've followed the "memory-hog" threads of late, but as a rather inexperienced Linux person, some of it is over my head. I'm using SA v2.64 with network tests and bayes. Everything is fine except that several times a day the server seems overwhelmed with load averages 4-12. Here is a minor example hitting 4.29:
07:45:01 runq-sz plist-sz ldavg-1 ldavg-5 ldavg-15 07:55:01 0 60 0.07 0.09 0.03 08:05:01 2 58 0.00 0.00 0.00 08:15:01 2 58 0.00 0.00 0.00 08:25:01 2 58 0.00 0.00 0.00 08:35:01 2 63 0.02 0.01 0.00 08:45:01 2 58 0.00 0.00 0.00 08:55:06 0 75 4.29 2.48 1.02 09:05:01 0 58 0.00 0.42 0.63 Average: 2 59 0.12 0.08 0.04 When the high LA hits, available RAM is essentially nil and the swap space is about 85% used as well. When I've seen it hit 12 or so, it seemed that the HDD activity would never stop, and I've manually killed spamassassin and any spamd's. This is on a recent Dell 400SC with 512 MB RAM and IDE drives. I suppose this might be a ridiculous question to some of you, but can you make an "experienced guess" as to whether the high load averages are due to my using network tests, due to insufficient RAM, or other? It -is- related to SpamAssassin, not some other process running on the machine. This is a small-scale family server receiving only about 250 emails a day. I'm using a simple postfix/procmail/SA setup. Procmail calls spamc. I guess I wouldn't have expected to see these load averages on such a small-scale server. Thanks any tips! - John
