DO NOT REPLY [Bug 46785] New: Child process increases to 100% (CPU)
https://issues.apache.org/bugzilla/show_bug.cgi?id=46785
Summary: Child process increases to 100% (CPU)
Product: Apache httpd-2
Version: 2.2.3
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Event MPM
AssignedTo: bugs@httpd.apache.org
ReportedBy: est-c-marinho@ptinovacao.pt
Using Apache 2.2.3 acting as a proxy, renamed here as wap2d, i'm getting some
process at 100% of CPU.
Some times it crashes at apr_brigade_cleanup () and others at
apr_bucket_destroy_noop () (see gdb backtrace bellow).
Other times i get a segmentation fault but the core dump file says the same.
I hope that someone can help.
Here is the gdb backtrace:

I suggest moving to the current release (2.2.11 at the moment). If you still
have problems, try commenting out all the modules you're not using. If that
doesn't help, you'll probably have to provide your exact configuration and
detailed instructions for recreating the problem for someone to be able to
help.
All I can tell from the stack trace is that something probably corrupted memory
at some time in the past, and apache tripped over it when it tried to clean up
during a normal shutdown. So you might be able to catch the problem by
building APR with malloc and pool debugging enabled.
