Am getting a lot of these in our error log

((11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread) and (110)Connection timed out: proxy: HTTP: attempt to connect to 127.0.0.1:80 (*) failed

The parameters of the worker in httpd.conf are as follows

StartServers 8
ServerLimit 128
MaxClients 2048
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 32
MaxRequestsPerChild 10000

I have changed the stack size in limit.conf but still not helping , Can anyone please help me ?

Update 04/04/2011: After Working on this Issue We have changed the configure file to the following

StartServers 8
ServerLimit 64
MaxClients 2048
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 32
MaxRequestsPerChild 0
ListenBacklog 2048

And the connection error to localhost disappear We had to set MaxRequestPerChild to zero and we changed number of user's processes in the limits.d/90-nproc.conf

* soft nproc 40000
