The virtual private server (VPS) software that pmwiki.org is under watches memory usage, and when it exceeds a certain threshhold limit (burst mode) the controller starts killing off processes somewhat randomly to bring total memory usage back under the limit. Other processes run from time to time to bring key services (such as the webserver) back online if they were killed. I've never been able to determine exactly what causes the server to hit the limits. I know that some of the automated cpanel updates and system maintenance utilities often cause the memory limit to be exceeded (which I find frankly annoying, since I don't have much control over those). Also, if pmwiki.org (or the other sites I host on the VPS) gets flooded with a lot of HTTP requests (e.g. from poorly-behaved spiders) then memory usage can go up dramatically as well. This is especially true if those requests are for things like pagelists and search results that require a lot of memory to generate. I just checked with my service provider, and they apparently have new hosting packages that eliminate the burst mode problem and are also $30/mo *cheaper* than what I currently have. So, the solution looks to me like I should migrate pmwiki.org and my other sites to a new server package, and this should resolve a lot of our service issues. (It would also upgrade me to later versions of the OS and control panels and give me a good reason to clean up many things on the overall system, which should increase security and performance a fair bit.) I'll work on that over the next few days. Pm ___ pmwiki-users mailing list pmwiki-users@pmichaud.com http://www.pmichaud.com/mailman/listinfo/pmwiki-users

Both CPUs show 78%+ idle... lots of free memory... I'm just not seeing much of anything. Maybe when the smtp wakes up to handle mail... perhaps something happens then but it's not obvious to me that is causing any problem. ___ pmwiki-users mailing list pmwiki-users@pmichaud.com http://www.pmichaud.com/mailman/listinfo/pmwiki-users
