[users@httpd] rotatelogs and cronolog don't die!
Hi,
I'm having the same problem on both Apache 2.0.47 and 2.0.48
with both cronolog and rotatelogs. Both them are running on
Slackware 9.1 with customized kernel.
The problem is:
When Apache starts, it starts all cronolog (or/and rotatelogs) "instances"
correctly, but,
when I stop Apache, all cronolog (or/and rotatelogs) instances remain
running (not zombie).
And starting Apache again, it starts another set of instances of cronolog
(or/and rotatelogs),
leaving a lot of cronologs running on the system.
[]s,
Herbert

I suppose if you want to debug this more you should write a simple perl
script that does nothing other than sit there and log all signals
received. When Apache is going down it should send a SIGTERM to the
program that it has invoked, or at least close the pipe and send
SIGPIPE. If the program is not receiving these signals then it could be
an Apache thing.

New information
Correction:
After stoping Apache, the pipe log programs stops too, but Apache forks
another set of them
before stoping itself.

Perhaps it is a genuine bug then - certainly works very well in my
experience (cronolog and a custom perl loggging daemon via a pipe) on 1.3.x.
Would be useful to hear from other 2.0 users who use piped logging eh?

Just a new information...
The problem is generalized to any "piped log program".
I tested with a simple grep command as a piped log program and it remains
running after Apache is stoped.

Re: [users@httpd] rotatelogs and cronolog don't die!
Posted by "Herbert G. Fischer" <he...@trama.com>.
The problem is not directly with cronolog because I'm having the same
problem with rotatelogs.
I think that is something with Apache related to the standard libs from
Slackware 9.1 because on Suse 7.3 PPC + Apache + Cronolog I don't have this
problem.
The same problem was reproduced on another machine with Slack 9.1 and Apache
2.0.47.
I'm trying to understand Apache source to do some tests but I'm getting very
confused.
I discovered that attaching strace to the main apache process and stoping
apache, all "piped log programs" stops, maybe because Apache has some
slowdown by the strace debug.
Thanks for your help.
I already had posted a bug report but I got no answers there.

Apologies I misread your last post :( Have you tried rebuilding

Are you sure you have the "|/path/to/cronolog" part in the customlog
line? It sounds as though you're piping the errorlog directly to the
file (template) /usr/local/sites/portal/logs/access.%Y-%m-%d.log instead of:
/path/to/cronolog /usr/local/sites/portal/logs/access.%Y-%m-%d.log
sample cronolog customlog line:

I activated debug on Apache and discovered the following errors:
piped log program '/usr/local/sbin/cronolog
/usr/local/sites/default/logs/access.%Y-%m-%d.log' failed unexpectedly
piped log program '/usr/local/sbin/cronolog
