*Basics:* Tomcat 6.0.20 (5 instances) Apache 2.2.13 using mod_proxy_ajp to connect to the tomcat instances Dell Poweredge 1950 running Fedora Core
We're noticing that we frequently have a buildup in the morning of AJP errors in our apache error_log along the following lines: *[Wed Feb 16 04:43:35 2011] [error] ajp_read_header: ajp_ilink_receive failed [Wed Feb 16 04:43:35 2011] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (127.0.0.1) [Wed Feb 16 04:45:23 2011] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [Wed Feb 16 04:45:23 2011] [error] ajp_read_header: ajp_ilink_receive failed [Wed Feb 16 04:45:23 2011] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (127.0.0.1) [Wed Feb 16 04:45:23 2011] [error] [client hidden] proxy: error processing end [Wed Feb 16 04:47:44 2011] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [Wed Feb 16 04:47:44 2011] [error] ajp_read_header: ajp_ilink_receive failed [Wed Feb 16 04:47:44 2011] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (127.0.0.1) [Wed Feb 16 04:52:06 2011] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [Wed Feb 16 04:52:06 2011] [error] ajp_read_header: ajp_ilink_receive failed [Wed Feb 16 04:52:06 2011] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (127.0.0.1) [Wed Feb 16 04:54:34 2011] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header* I'm trying to get a handle on what's going on here and how to fix it. I've not yet found anything in the tomcat logs of concern. Can anyone give me some idea of what's going on or how to remedy it? Not really sure what the next step in troubleshooting is at this point. Thanks all for your help, Shaun
