Summary: threads locked at logging state
Product: Apache httpd-2
Version: 2.2.4
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Event MPM
AssignedTo: bugs@httpd.apache.org
ReportedBy: kylewong@southa.com
I've setup a new webserver serving status images with linux kernel 2.6.19 and
apache 2.2.4. This is the first server I experiment with the new "event mpm".
I found that after it has up for several hours, there's many threads locked at
"logging" state. I have many other servers running apache 2.0.x series (worker
mpm) doesn't have the same problem. I GUESS it's related to the new event mpm?
but I haven't try 2.2.4 with worker mpm yet.

I've committed a potential fix to trunk with r567852:
https://svn.apache.org/viewvc?view=rev&revision=567852
The approach is different form the patch attached here -- it avoids rewriting
the loops.

Server status report (PDF)
This bug (41712) is also present in Apache 2.2.4 for OS/2. And if this error
occurs, the website cannot be accessed anymore. But more importantly, the
process can not be killed in any way. Even C-A-D doesn't work. Only a reset of
the PC will bring back control. This makes the error severe!
