>Description:
===================
httpd processes are eating all CPU cycles and spirals down the server.
===================
e.g. 10(!) active httpd requests produce a high-level cpu usage (165% cpu usage
on a 3-cpu machine - shown by server-status).
We have 5 virtual servers up and running (3 web servers, 2 proxy servers).
There are no error log messages (nor apache logs, nor sys message entries, -
and hardware checks fine) concerning this problem.
We have tried out almost anything (changing Config,
playing with RLimitCPU, etc.).
Relevant parts of our apache Config FYI:
---------- snip ---------------
Timeout 300
KeepAlive On
MaxKeepAliveRequests 128
KeepAliveTimeout 15
MinSpareServers 4
MaxSpareServers 8
StartServers 5
MaxClients 150
MaxRequestsPerChild 128
#RLimitCPU 10 20
------------- snap ---------------
Any ideas to track down the problem? What can we do?
We have reported this problem ("server slow") also to Sun support.
The answer after some research by Sun was: httpd (apache) is the problem
(sic)...
