Hello: I've configured the mod_jk with the default configuration of 1.2.30 version, at the moment, the problem has not appeared , when it will appear I'll see that this solution works well.
Thank you so much for your help. -----Mensaje original----- De: Rainer Jung [mailto:rainer.j...@kippdata.de] Enviado el: viernes, 15 de octubre de 2010 11:26 Para: users@httpd.apache.org Asunto: Re: [us...@httpd] Reserving a thread for request against mod_jk in apache server.

No, either you have to detect the situation in advance, so that not all threads are aleady blocked - which under high load might be difficult - or you have to switch to other solutions: - configure better timeouts for mod_jk, so that those threads don't stay stuck. See for example the sample configuration contained in the mod_jk 1.2.30 source tarball download. The sample configuration in older mod_jk downloads is pretty outdated. - set activation for the broken Tomcat to "stopped" in the workers.properties and do a hard "restart" of Apache (which will also stop all other running requests, but in such a situation it is unlikely that the web server is still able to serve requests). In case there's more questions: the right list to discuss mod_jk is the Tomcat users mailing list.
