how to decide the correct value for connection_pool_size

[Rasmus - Next Stay A/S]

Hi 

 

I am running Tomcat 4.12, IIS 6.0 and newest JK. How do I determine the
correct values for

 

connection_pool_size

 

I sometimes get this error:

 

[Sat Jul 14 10:19:19 2007] [1388:5176] [error] jk_isapi_plugin.c (1507):
Failed to obtain an endpoint to service request - your
connection_pool_size is probably less than the threads in your web
server!

 

My current values are:

 

worker.worker1.connection_pool_size=30

worker.worker1.connection_pool_minsize=16

worker.worker1.connection_pool_timeout=600

 

shouldn't this be enough. Does anyone have any experience in this?

 

Thanks,

 

Rasmus

Hi

 

I am seeing this error in my isapi.log, I am running IIS 6.0, tomcat 4.1
and jk 1.2.23

 

...[5228:6988] [error] jk_isapi_plugin.c (1507): Failed to obtain an

Does anyone know what this means, and what the cure is?

 

Thanks,
