DO NOT REPLY [Bug 52485] New: CPU load 100%
https://issues.apache.org/bugzilla/show_bug.cgi?id=52485
Bug #: 52485
Summary: CPU load 100%
Product: Apache httpd-2
Version: 2.2.21
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy
AssignedTo: bugs@httpd.apache.org
ReportedBy: paak01@handelsbanken.se
Classification: Unclassified
Hi,
We installed a APACHE 2.2.21 and used it as a proxy. When a call was made the
CPU raised to 50-100% and stayed there. After backing to 2.2.15 the problem was
solved. We also saw that if hade more modules loaded the problems increased.
httpd.conf
"ServerName xxx.xxx.xx:80
Listen 8080 443
LoadModule authz_host_module modules/mod_authz_host.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
<IfModule mod_proxy.c>
ProxyRequests On
ProxyVia On
<Proxy :*>
Order deny,allow
Deny from all
Allow from xxx.xxx.xx
</Proxy>
</IfModule>
AllowCONNECT 443 49171"

Specify your platform and post a backtrace from the server at 100% CPU.

I have the same problem, with the apache embedded in wamp.
Version of Apache is 2.4.2.
Suddenly the CPU load raises to 100 %.
But it seems also that after a certain time quite long, the problem stops and
starts again.
I noticed also that in this king of situation some connections are in
closewait, which means that the thread is occupied to do something else. The
same number of connections is established with the backend, probably the
modproxy connected to a backend.
I suspect the connected mode to be the reason as the problem seems to occur
more often when browsing https sites.
I do not know what information to provide to you, but my configuration is very
simple, and I can give you the httpd.conf and httpd-vhosts.conf files: The only
files I changed.
I try to have a proxy on my PC that rewrite some URL and block some sites to
block the tracking and some advertisement. Only the current user only induces
the load.
My configuration is windows 7 64 premium French
Intel i7 920 QM
WampServer 2.2, Apache 2.4.2
