Interesting. What about the access log? Does JBoss even admit to accepting the request? The access log ,shows time of request received (%t), as 15:31:53 2015 , with 300 seconds as the time taken to serve the request (%D). But this line is actually printed 5 minutes afterward with other requests which were received at 15:36:48 , and also it shows 400 as status. Another thing I notice in the modjk.log, is that for this request, I only see the request header getting printed, don't see any body getting printed in the logs. On Jboss logs, I can see the request coming in, wait for 5 minutes and then process the request successfully. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v2 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJVOkHxAAoJEBzwKT+lPKRYrmAQAMBt4sgatAgrqHdSR9KxzYCo lUbdUjuQ+lGi/nCc/HALcDjVRTtbagSMsTcJxl5uzpUn9JbAwUN/+ERCh8mSMLyH jqIzrJD+lGJc+b5Eff6je3OFxZznpoieiN89oaodemVQzJW7oCSG5SNiYYqN6sBD cE01OE+V6sSohmqRNQ3Ieh4Maz4X9/J6qD2sq9ax+r5b71jZHeA6BK9//XOgolyV MeUSAuSC41ZnzdTMDozj8hrszilI5keBp4lWE0oIJJ7nHlkpqE0Zi13CN8NASUni Z2QQRu+SjVf5EHY9Cjek+qdr5z2HGdjQyxBIz7RW2a1EKH8jCU5f5tlb3Mjl2++k DywPlqfnJCeA03PPLuCnbiFW+M1M4JOoLrhKudwkKdsWz7SuURY1xy8G7ufue/ed 2d6hPINwVUb5Fr/FI7s2hj7ItZzx5IQ2DxSSCwdV3Ts0ePTK/acRKhu22lFfH0BH YnshsMkLrja7LlV5SpZeB9oCyPZl0ecoPnCy3K8sBdnDDGOddwflnSn97jgLRK+/ j1Rr9CT+DXQLgiWeFnJZJ5Fq5HCG1EzoidZ4KBeMWQpxGr1ukmhxDbMkWMUE87X2 ycG+GGAZ0x+xA0R8xyeN65hP/7cS+07FMHdKdw7rZAmf6BWyxC5FxFerVWRM2hPY IP4OKOfiXwivGBDwIgCC =ZBL9 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I wiill get this trace out I don't see anything immediately obvious. Do you have a firewall between httpd and Tomcat? Has it been configured to leave the connections open forever? If not, you might want to consider configuring CPING/CPONG at intervals (look at the AJP connector configuration reference and search for cping/cpong to see how to do that ). will check for the firewall and revert.

Apache Tomcat jk connector 400 bad request
Hi there, I would like to explain my scenario, perhaps this has been answered on this forum. A bunch of random Ajax requests from the browser (IE9) end up with a 400 error code on the apache webserver and the the browser hangs for 5 minutes. Httpwatch shows the error code as ERROR_INTERNET_CONNECTION_RESET and then immediately afterwards IE fires the same request again, which shows up with a time taken of 5 minutes and error code as ERROR_HTTP_INVALID_SERVER_RESPONSE. The browser recovers after 5 minutes. Further investigation on the webserver and appserver logs reveals the following:: a.. The request comes from the browser and hits the webserver and then forwards to the appserver instantly. b.. The mod_jk log for the request shows that there is time duration of 5 minutes spent in the ajp_read_fully_server::jk_ajp_common.c(1399): enter. After 5 minutes I get the next line as follows ajp_read_fully_server::jk_ajp_common.c(1432): exit. Then in the next line i see the following ajp_send_request::jk_ajp_common.c(1766) worker 11 browser stop sending data, no need to recover. Later it shows unrecoverable 400, request failed. c.. The forensic.log show the content length as a nonzero value. d.. The applcation server log hangs in the org.apache.coyote.ajp.AjpProcessor.read method for 5 mintues and the continues the execution. The thread dump also confirms this. The questions I have are:: a.. Is this a problem with IE only because of the keepalive timeout and the apache webserver keepalive time(current value is set to 5seconds) out which is not in sync. b.. Is this a problem with the appserver not able to process requests that are bad/incomplete. c.. Should I increase the Apache webserver timeout value to 60s or more , will this have any performance impact. Kindly advise on the scenario. Many thanks for reading through.
