Dear Colleagues We installed apache with mod_jk that connected to tomcat workers on the different machine, during monitoring the received requests we notice the below error on mod_jk log, and after checking the worker log we find the request received and logged in the access-log of the worker but the main problem is Tomcat Instance is working and running while the apache shows the below error.
also I requested static object from Tomcat worker , and the below error didn't appear in modjk logs [Sat Nov 03 13:06:20 2018][54448:140562048997120] [warn] ajp_get_endpoint::jk_ajp_common.c (3372): Unable to get the free endpoint for worker worker_app1 from 1 slots [Sat Nov 03 13:06:20 2018][54448:140562048997120] [info] service::jk_lb_worker.c (1343): could not get free endpoint for worker worker_app1 (0 retries) [Sat Nov 03 13:06:20 2018][54448:140562048997120] [info] service::jk_lb_worker.c (1650): All tomcat instances failed, no more workers left for recovery (attempt=1, retry=1) [Sat Nov 03 13:06:20 2018][54448:140562048997120] [info] service::jk_lb_worker.c (1670): All tomcat instances are busy or in error state [Sat Nov 03 13:06:20 2018][54448:140562048997120] [error] service::jk_lb_worker.c (1675): All tomcat instances failed, no more workers left
