[Bug 54118] New: Handle leak on parent httpd process when rotatelogs
is used with CustomLog directive
https://issues.apache.org/bugzilla/show_bug.cgi?id=54118
Priority: P2
Bug ID: 54118
Assignee: bugs@httpd.apache.org
Summary: Handle leak on parent httpd process when rotatelogs is
used with CustomLog directive
Severity: normal
Classification: Unclassified
Reporter: carpentier@ipanematech.com
Hardware: PC
Status: NEW
Version: 2.4.3
Component: Core
Product: Apache httpd-2
Created attachment 29570
--> https://issues.apache.org/bugzilla/attachment.cgi?id=29570&action=edit
apache conf file
With apache 2.4.3 Win32 (Apache Lounge Distribution, Apache 2.4.3 win32, IPv6
and Crypto enabled, apr-1.4.6 apr-util-1.4.1 apr-iconv-1.2.1 openssl-1.0.1c
zlib-1.2.7 pcre-8.30 libxml2-2.7.8 lua-5.1.5 expat 2.1.0).
The leak on the parent process appear when the child httpd process is recycled,
so configure mpm_winnt_module with MaxConnectionsPerChild = 100:
<IfModule mpm_winnt_module>
ThreadsPerChild 150
MaxConnectionsPerChild 100
</IfModule>
In httpd.conf, configure ErrorLog and CustomLog to use rotatelogs program:
ErrorLog "| bin/rotatelogs.exe logs/error.%Y-%m-%d.log 86400"
CustomLog "| bin/rotatelogs.exe logs/access.%Y-%m-%d.log 86400" common
Start apache
Using "handle" program from sysinternal, execute "handle -s -p <httpd parent
pid>"
In apache/bin directory, execute "ab.exe -n 100 http://localhost/"
Rexecute "handle -s -p <httpd parent pid>"
Compare the 2 results:
- in the first I have: "22C: Process rotatelogs.exe(7956)"
- in the second I have: "22C: Process <Non-existant Process>(7956)"
And to confirm it's due to rotatelogs used with CustomLog, comment the
"CustomLog" line in httpd.conf and retry => no handle leak on the parent httpd
process.
