hi

i m using jboss4.2.2.GA and ocle 10g

OS : RHEL5

Problem Description:
Users get a 503 error message when the try to login in to the website. it seems they cannot connect to the Application via ajp proxying.

1. My apache error_log looks like this when the 503 issues are occuring..

[Mon Nov 24 16:35:06 2008] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header
[Mon Nov 24 16:35:06 2008] [error] ajp_read_header: ajp_ilink_receive failed
[Mon Nov 24 16:35:06 2008] [error] (120006)APR does not understand this error code: proxy: read response failed from 127.0.0.1:8009 (localhost)
[Mon Nov 24 16:35:55 2008] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header

2. All TCP connections in CLOSE_WAIT are owned by Jboss.
[root at l194t08 ipv4]# /usr/sbin/lsof -i -nP |grep CLOSE_WAIT
java 9765 jboss 17u IPv4 4902598 TCP 127.0.0.1:8009->127.0.0.1:47019 (CLOSE_WAIT)
