Everything is working but from time to time we can not connect anymore through the IIS. Accessing Tomcat directly to port 8080 is working. </p> <p>The errorlog has the following entries: </p> <p>[Wed Aug 13 11:46:17 2008] [warn] ajp_get_endpoint::jk_ajp_common.c (2138): Unable to get the free endpoint for worker ajp13w from 10 slots [Wed Aug 13 11:46:17 2008] [info] ajp_get_endpoint::jk_ajp_common.c (2152): can&#39;t find free endpoint [Wed Aug 13 11:46:17 2008] [info] service::jk_lb_worker.c (629): could not get free endpoint for worker ajp13w [Wed Aug 13 11:46:17 2008] [info] service::jk_lb_worker.c (712): All tomcat instances are busy or in error state [Wed Aug 13 11:46:17 2008] [error] HttpExtensionProc::jk_isapi_plugin.c (1022): service() failed If we bounce IIS, then we can get back in again until happens again. Anyone know how to resolve this issue? </p>
