[DRE-maint] [Bug 1026601] Re: passenger-status no longer works after upgrade to precise

[Michael Mönch]

The problem seems to be with the PID that is used for the temp-
directory:

ps:
root      7558     1  0 14:35 ?        00:00:00 /usr/sbin/apache2 -k start
root      7572  7558  0 14:35 ?        00:00:00 /usr/lib/phusion_passenger/ApplicationPoolServerExecutable 0 /usr/lib/phusion_passenger/passenger-spawn-server  /usr/bin/ruby  /tmp/passenger.7538

The directory should be /tmp/passenger.7558 (the PID of the Apache main
process) not 7538. If you rename the directory you can successfully
execute the passenger-status program and it will return the correct
information. But I don't know if this will break the application at some
other point.

  passenger-memory-status also doesn't appear to be working as expected.
