[AMaViS-user] saving memory
Hello amavis users, I have noticed a huge amount of swap usage (around 150 MB with 512 MB of physical RAM). So now I am trying to save memory as much as possible. I reduced $max_servers to 1 in amavisd.conf as supposed in the README.performance file. After a restart of amavisd-new swap usage went down under 100 MB. Besides the daemons that I need for mail, the machine runs bind, apache and mysql. I also limited memory usage for those programs as good as I can. This brought me down to around 20 MB in swap. The problem is, that over time I still get over 100 MB swap usage. Obviously amavisd-new is to blame because when I just do a restart of it, I get down to the 20 MB swap. What I also noticed is, that there are 2 amavisd-new processes after my max_servers reduction (from above). Can I run amavisd-new with $max_servers = 0? Which other measures do you know to limit or to save memory? I am using amavisd-new-20030616p10-5 with spamassassin-3.0.3-1 and clamav-0.85.1-2 connected to exim-3.35-1 on a Debian woody. (I know that these are very old versions) TIA Timo --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ AMaViS-user mailing list AMaViS-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amavis-user AMaViS-FAQ:http://www.amavis.org/amavis-faq.php3 AMaViS-HowTos:http://www.amavis.org/howto/

And, I was planning to use qmail's default rcpthosts file as the base template (spam_lovers_maps) for the domains and any exceptions to the base config should go into the spam_haters file (default should be to pass spam). Any ideas for such setup? Thanks, Nicklas I assume then that the /lovers will contain a list of domains. This works. You simply have to manually add full email addresses to the haters file, followed by a zero. Haters will be read first, because it is listed first. If a match is found, the search should end there. The period at the end means everyone not listed is also a lover. @spam_lovers_maps = ( read_hash(/spam_haters), read_hash(/spam_lovers), . ); /haters [EMAIL PROTECTED] 0 /lovers example.com My last reply was rushed and possibly inaccurate. I think the . should have been a 1. @spam_lovers_maps = ( read_hash($MYHOME/spam_haters), 1 ); May be better. If all domains will be spam_lovers by default, then there is no need to look them up, simply make everyone a lover, and list only the exceptions. Contents of the spam_haters file: # we have set @spam_lovers_maps = ( read_hash($MYHOME/spam_haters), 1 ); # which means everyone is a spam lover by default. If you would like to # exclude a particular user from being a spam lover, include them in # this associative array using a 0 for the value. For example: # [EMAIL PROTECTED] 0 # [EMAIL PROTECTED] 0 Could you define a domain in the haters file instead of the whole email adress? Like: example.com 0 ? Thanks, Nicklas Yes, of course. Typically you would also include subdomains: .example.com 0 You could also make any number of users in that domain spam_lovers, if you needed to make exceptions for them: [EMAIL PROTECTED] [EMAIL PROTECTED] .example.com 0 From: http://www.ijs.si/software/amavisd/README.lookups.txt Hash lookups (e.g. for [EMAIL PROTECTED]) are performed in the following order: - lookup for [EMAIL PROTECTED] (only if $recipient_delimiter is '+') - lookup for [EMAIL PROTECTED] - lookup for user+foo@ (only if $recipient_delimiter is '+') - lookup for user@ - lookup for sub.example.com - lookup for .sub.example.com - lookup for .example.com - lookup for .com - lookup for .

Hopefully the spamassassin version you are using includes a patch for a known DOS vulnerability in 3.0.3. It looks like 3.0.4-1woody1 is available from backports.

What is much more important is how much swapping is happening as things are running, and whether or not that is impacting your ability to process email. You should look at the output that has been captured from your sar utility (sar -rW) and examine how swapping is occurring over time. Don't worry about what's swapped out to disk now, or the peak values. Trying to reduce processes to the point of starvation, etc. is not the best approach - rather, and I'm sure you know the drill, adding more RAM is the way to go. -mike --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ AMaViS-user mailing list AMaViS-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amavis-user AMaViS-FAQ:http://www.amavis.org/amavis-faq.php3 AMaViS-HowTos:http://www.amavis.org/howto/

[AMaViS-user] sql lookups for non-local recipients?
Howdy, I've been tweaking my amavisd-new config to try and get some efficiency savings. One thing I did was turn off spam scanning for non-local recipients via bypass_spam_checks_maps. This seems to work fine, but I see that amavisd is still attempting all the per-user sql lookups for non-local recipients, which always fail. Is there any way to prevent these lookups? If not, does this seem like a useful feature?

Don't worry about what's swapped out to disk now, or the peak values. When I first saw how much swap is beeing used I was a little scared and my only thought was of how to reduce it. The higher the amount of used swap, the worse it is for the system I thought. I still believe that this is right, but I also found a chapter about memory management in Linux System Administrators Guide. Now I see that you are right, it's more important to monitor swapping over time periods. I ran sar, but I don't have enough other values to compare them. Here are my daily average values for pswpin/s and pswpout/s. # for x in /var/log/sysstat/sa[0-9][0-9]; do sar -W -f $x | grep ^Aver; done Average: 0.78 0.00 Average: 1.41 0.00 Average: 3.23 0.11 Average:10.32 0.22 Average:17.49 0.02 Average:15.87 0.03 Average:27.74 0.06 Average:18.13 0.26 Average: 6.88 0.12 Average: 4.28 0.07 Is that good or bad? I have another system with sar activated but I only get zeros. So no swapping seems to be done there. Trying to reduce processes to the point of starvation, etc. is not the best approach - rather, and I'm sure you know the drill, adding more RAM is the way to go. Adding more RAM is my last resort. The system is in production and it is not so easy to have down times. Of cource, if anything else fails, I will go that way. But maybe the values that I have written above aren't so bad and I can live with that swap behaviour? Eventually I have learned that swapping in general is not necessarily bad.

I believe the same would happen if you restarted other (large) programs too. Ok, that is probably true. I didn't try others at that time.

RE: [AMaViS-user] saving memory
When I first saw how much swap is beeing used I was a little scared and my only thought was of how to reduce it. The higher the amount of used swap, the worse it is for the system I thought. I still believe that this is right, but I also found a chapter about memory management in Linux System Administrators Guide. Now I see that you are right, it's more important to monitor swapping over time periods. Exactly - some swapping is normal, and small amounts of occasional swapping is no problem. In fact, it helps out poorly written programs where the programmers don't bother to properly manage memory, in that it dumps out the pages from the working set that are not frequently used. I ran sar, but I don't have enough other values to compare them. Here are my daily average values for pswpin/s and pswpout/s. # for x in /var/log/sysstat/sa[0-9][0-9]; do sar -W -f $x | grep ^Aver; done Average: 0.78 0.00 Average: 1.41 0.00 Average: 3.23 0.11 Average:10.32 0.22 Average:17.49 0.02 Average:15.87 0.03 Average:27.74 0.06 Average:18.13 0.26 Average: 6.88 0.12 Average: 4.28 0.07 Is that good or bad? I have another system with sar activated but I only get zeros. So no swapping seems to be done there. The average values here are not as useful as individual values, as they tend to hide the extremes (for example, lots of 0 page swaps and one or two 200 page swaps). They will tell you as a trend if your system is overloaded, but not anything about the occasional swap peaks and thrashing. You need to look at the individual values to see if you have extreme highs. Each unit is a page, which is 4k bytes, so I see on one day you had an average 112k of swap / second. This is higher than you'd want. My average for example is .024, and never gets above 4. And your heavy load is swapins, which means either you have processes that are periodically spiking to get their working sets, or you have very heavy swap in requirements during boot, and then little afterwards. Again, you need to examine the numbers. Trying to reduce processes to the point of starvation, etc. is not the best approach - rather, and I'm sure you know the drill, adding more RAM is the way to go. Adding more RAM is my last resort. The system is in production and it is not so easy to have down times. Of cource, if anything else fails, I will go that way. But maybe the values that I have written above aren't so bad and I can live with that swap behaviour? Eventually I have learned that swapping in general is not necessarily bad. Understood - nobody ever wants downtime. Yet, a 30 minute scheduled downtime for a RAM upgrade is far more tolerable and safer than mucking with various daemon configurations on a production system that you don't understand well, right? And in the end, you have a stronger work horse.
