[Bug 60825] New: [core:emerg] File exists: AH00023: Couldn't create
the watchdog-callback mutex (file /var/run/watchdog-callback-_proxy_hcheck_)
https://bz.apache.org/bugzilla/show_bug.cgi?id=60825
Bug ID: 60825
Summary: [core:emerg] File exists: AH00023: Couldn't create the
watchdog-callback mutex (file
/var/run/watchdog-callback-_proxy_hcheck_)
Product: Apache httpd-2
Version: 2.4.25
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy_hcheck
Assignee: bugs@httpd.apache.org
Reporter: rustamabd@gmail.com
Target Milestone: ---
mod_proxy_hcheck in 2.4.25 causes httpd to terminate on SIGUSR1.
How to reproduce:
1. install httpd 2.4.25 (tried on FreeBSD 11 amd64)
2. enable modules:
LoadModule watchdog_module libexec/apache24/mod_watchdog.so
LoadModule proxy_module libexec/apache24/mod_proxy.so
LoadModule proxy_hcheck_module libexec/apache24/mod_proxy_hcheck.so
3. start httpd
4. Send a graceful restart signal (USR1) to httpd:
kill -30 `cat /var/run/httpd.pid`
5. Notice httpd alive no more.
Error log contains:
[Mon Mar 06 21:30:16.675109 2017] [mpm_prefork:notice] [pid 1911] AH00171:

Does the file exist? It looks like this is due to the graceful restart and the
file not being cleaned and/or ignored

https://svn.apache.org/viewvc/httpd/httpd/trunk/modules/proxy/mod_proxy_hcheck.c?r1=1784275&r2=1785871&diff_format=h
proposed for back port
