Bob, I've seen the same thing happen with the Original server on a single processor 840 partition with 2gb memory under V5R1. It never had a problem with static content (SSI's even worked okay) but once we started with heavy CGI loads, we began having problems (I was on the phone a lot with IBM in the months prior to our switch). We haven't had a single problem with the HTTP server since switching over to the Apache based server. As far as volume goes, we typically do a couple thousand hits an hour to dynamic content (simple SSI's, Net.Data, RPG CGI, and Java) and I'd be surprised if there are more than a handful of pages on any of the sites on that box that are purely static. We have 7 HTTP server instances running (5 Apache, 2 Original) which serve 14 websites (one Apache instance has 11 virtual sites and two of the instances handle SSL traffic), WAS 3.5 SE with 4 running servlet engines, and we also run FTP (this is low volume, we only do about 1000 FTP hits per day).

The cause for this was due to extremely high volume of hits during a 2 hour period. When my free email newsletter went out last night and everybody on the east coast got in this morning, the server started to get very, very busy. In about a 90 minute period we had nearly 5,000 hits on the website. The entire system slowed to a crawl and the webserver pages were effectively not being served to the web users. My theory is that too many server jobs were being started for the system capacity and some CGI jobs where starting/ending so quickly with each hit that the system just couldn't keep up. Now I have been lobbying to upgrade to V5R1 and go to the Apache server but haven't been able to get the hosting agent to do that yet (after all RPGIV.com is a free site that produces no revenue). So my question is, have others had this kind of thing happen on their systems? Can the 400 handle 5,000+ to 10,000+ hits per hour on an entry-level machine? -Bob Cozzi _______________________________________________ This is the Web Enabling the AS400 / iSeries (WEB400) mailing list To post a message email: WEB400@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/web400 or email: WEB400-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/web400.
