      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
      [Mon Nov 24 16:35:55 2008] [error] ajp_read_header: ajp_ilink_receive failed

      2. All TCP connections in CLOSE_WAIT are owned by Jboss.
