Hi Mani, The fact that the issue is occurring with Resin 4 also leads me to think it's not an issue related to Resin at all. It could be something related to Apache. It would help you can take that out of the equation but accessing Resin directly. The only other possibility that occurs to me right now is database lock contention for the same rows, since you say it's occurring when the same users connect.

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.

Hi Mani, A 503 error usually indicates Resin was unavailable to Apache (ie restarting) or overloaded. The client IP address should not matter. You need to examine the Resin logs to see what is it doing during that time and if there are any errors reported. Resin may be running out of resources or paused for a long garbage collection. Often simply increasing thread-max to a larger number like 2048 helps, since the default is rather low for Resin 3.1.

I have tried manually and by using the setup.exe program, but cannot get it to work. I try to launch Apache, it fails to start-up. Looking at the Event Viewer, I see the error message "Syntax error on line 115 of C:/ tech/apache/conf/httpd.conf: Cannot load C:/resin-3.0.14/win32/ apache-2.0/mod_caucho.dll into server: The specified module could not be found." You need to get Resin 3.0.23 and use the apache-2.2 mod_caucho. The DLLs for Apache 2.0 and 2.2 are not compatible. -- Scott But the file definitely exists. Could it be that for some reason it isn't recognised as a valid module? This may be a question for the Apache community, but just in case there is a known issue with this version of mod_caucho.dll, I thought I'd write here. Details are: Resin 3.0.14 Apache 2.2.4 on Windows XP. mod_caucho.dll is timestamped (last modified) 31 August 2006, 09:17:10 Entries from httpd.conf (all paths correct): LoadModule caucho_module "C:/resin-3.0.14/win32/apache-2.0/ mod_caucho.dll" AddModule mod_caucho.c ResinConfigServer localhost 6802 CauchoStatus yes Any ideas?
