Re: [Resin-interest] apache resin 503 error when repeated requests from the same IP
Paul Thank you. Currently thread max is at 1400. Strange thing is, this happens on two pages where the user posts data repeatedly. Some of these IP addresses also repeating in the log. And, there are no issues with the page java code. In my previous setup, I did not gave this problem. I moved to new box and I keep the same resin configuration. However, I switched to worker RPM in apache and using JDK 1.7 . I dont see any errors in resin log. I tried to migrate 4.x version and getting the same problem. thanks Mani On Fri, Aug 17, 2012 at 12:09 PM, Paul Cowan wrote: > > On Aug 17, 2012, at 11:58 AM, Manidhar gudavalli wrote: > > HI > I am seeing a strange 503 error on the server.

[Resin-interest] apache resin 503 error when repeated requests from the same IP
HI I am seeing a strange 503 error on the server. When the repeated requests coming from the clients with the same IP address, after some time, I am seeing 503 error in apache logs. These requests are all valid requests from valid ips. I am using resin 3.1.12. and apache 2.2.3 and JDK 7. Is resin considering, the repeated request from same IP as spam? Is there any parameter that I can set to force resin to accepts the requests and not consider as spam? Please help. thanks Mani ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] 503 errors with apache resin connections
I am using apache 2.2.22 and resin 4.0.29 version in linux on the the new server. Once in a while, I see 503 errors in errors_log of apache. After research, I realize that, this is happening when ever resin takes couple of seconds to respond to a request. What configuration will fix this problem? I used to have same issue with resin 3.x version, after increasing socket time out the problem was solved. I am using the same setting in rein 4. in server-default I have these settings: 120s 1400 120s thanks Mani ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] File does not exist in Error Logs
I am using Apache/2.2.20 and resin 3.1.12 . Recently, I am seeing lot of strange errors in Apache error_logs. I dont see an issue to access the website. However in the logs, I do see in this format. When the user request for a page /test/data/ , the below error appears some times in the logs. Apache looks for random number file (9780) in the directory. This is happening to all files, and is very random. [Sun Apr 22 09:07:44 2012] [error] [client 11.777.477.431] File does not exist: /home/myaccount/public_html/test/data/9780, referer: http://www.mydomain.com/test/data/ Is it happening because of misconfiguration of Apache/resin? thanks Mani ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
