kind Sir/Madam, This problem has fixed itself twice and now appeared again I'm running on Solaris 2.6, Tomcat 3.2.1, Stronghold 3.0 (secure apache). I've been running happily making and testing servlets using ajp12 and ajp13, then it stops working. I start tomcat, start stronghold, try the servlet and get the following in mod_jk.log (set to debug) each time I try a page on tomcat. Bizarre - if I wait for a while I get java.io.IOException on the command line. I get the following errors in mod_jk.log when set to debug. [jk_uri_worker_map.c (344)]: Into jk_uri_worker_map_t::map_uri_to_worker [jk_uri_worker_map.c (434)]: jk_uri_worker_map_t::map_uri_to_worker, done without a match [jk_uri_worker_map.c (344)]: Into jk_uri_worker_map_t::map_uri_to_worker [jk_uri_worker_map.c (406)]: jk_uri_worker_map_t::map_uri_to_worker, Found a match ajp12 [jk_worker.c (123)]: Into wc_get_worker_for_name ajp12 [jk_worker.c (127)]: wc_get_worker_for_name, done found a worker [jk_ajp12_worker.c (223)]: Into jk_worker_t::get_endpoint [jk_ajp12_worker.c (121)]: Into jk_endpoint_t::service [jk_connect.c (108)]: Into jk_open_socket [jk_connect.c (115)]: jk_open_socket, try to connect socket = 9 [jk_connect.c (124)]: jk_open_socket, after connect ret = -1 [jk_connect.c (143)]: jk_open_socket, connect() failed errno = 146 [jk_ajp12_worker.c (134)]: In jk_endpoint_t::service, sd = -1 [jk_ajp12_worker.c (152)]: In jk_endpoint_t::service, Error sd = -1 [jk_ajp12_worker.c (163)]: Into jk_endpoint_t::done The first time I waited a while and it fixed itself. Restarting does not help (does it hinder?). This time, I wait a while, get the IO Exception, then try shutdown which fails (can't connect) then I try again and it starts working. I assume I can't get a socket for some reason but I'm sure I checked 'netstat -a' which showed no traffic on that port. Please can anyone tell me what is going on. Browsing the archives I see something about queues? I have to confess that I tend to not bother restarting the webserver each time I restart tomcat (does this make any difference?) Thanks in advance, Jon. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
