Scripts written for pear's "system_daemon" refuse to fork off to form new process. This works well on my old server, but my new server is not having it. The daemon scripts run just fine in a shell and will run until I kill them. As a temporary workaround, I have the daemon running in a detached tmux shell, but this obviously isn't a long term solution.
Are there any known issues that prevent it from forking?
I have PHP 5
PHP 5.3.10-1ubuntu3.2 with Suhosin-Patch (cli) (built: Jun 13 2012 17:19:58)
and pcntl listed here loaded ini's
/etc/php5/cli/conf.d/pcntl.ini,
and here further down in php -i output
pcntl
pcntl support => enabled
and Pear
PEAR Version: 1.9.4
and Pear's system_daemon
pear/System_Daemon 1.0.0 1.0.0 Turn PHP scripts into Linux daemons
Any ideas what is going wrong here?
I can't post source, unfortunately, but I can say that all (including the examples in the documentation) system_daemon scripts refuse to fork.
As suggested by cweiske, I tried the pcntl example and it worked correctly
I also tried uninstall system_daemon, purging my pear installation with aptitude, restarting, re-installing pear, and re-installing system_daemon. This also had no effect.
I can duplicate this issue on other Ubuntu boxes 11.04+
Issue resolved.
1) My appName property had an uppercase letter in it, which newer versions of system_daemon will complain about
2) I had installed pear and system_daemon before install pcntl. From the source this didn't look like it could cause an issue, but I re-installed both to be safe.
