Hello We are getting unable to get the free endpoint and eventually resulting in a 500 (internal server error).
We are using apache 1.3.37 and mod_jk version is 1.2.15. Due to many reasons, we are not in a position to upgrade wither of these packages. [Fri Dec 08 01:34:09 2006] [18477:0000] [warn] ajp_get_endpoint::jk_ajp_common.c (2138): Unable to get the free endpoint for worker myWorker from 1 slots [Fri Dec 08 01:34:09 2006] [18477:0000] [info] ajp_get_endpoint::jk_ajp_common.c (2152): can't find free endpoint [Fri Dec 08 01:34:09 2006] [18477:0000] myWorker 0.000088 Under these situations, we also see that either jboss threads are processing for a long time OR a particular thread is idle for a relatively long time. I would really appreciate if someone can explain why this particular error occurs and how to remediate the problem. Currently we are restarting both jboss and apache but we are not able to get to the root cause of the problem. People who have got the same error earlier have suggested that we need to increase the cachesize OR the connection_pool_size of the worker. but mod_jk documentation says that it is not recommended to use cachesize more than 1 for apache version 1.3.x. I would really appreciate if anyone can suggest a remediation for this issue. Shekar ----------------- cachesize This directive has been deprecated since 1.2.16. Cachesize defines the number of connections made to the AJP backend that are maintained as a connection pool. It will limit the number of those connection that each web server child process can make. Cachesize property is used only for multi threaded web servers such as Apache 2.0 (worker), IIS and Netscape. The cachesize property should reflect the number of threads per child process. JK will discover the number of threads per child process on Apache 2 web server with worker-mpm and set its default value to match the ThreadsPerChild Apache directive. For IIS the default value is 10. For other web servers this value has to be set manually. Do not use cachesize with values higher then 1 on Apache 2.x prefork or Apache 1.3.x! --------------- Shekar
