Re: [monit] Start/Stop Program Calls in Monitrc

[bggy]

Thanks for the tip!  It seems that the other issue I'm having with the
workling and ultrasphinx start calls is related to Monit resetting
environment variables. When starting ultrasphinx I get the following error
message:

couldn't find HOME environment -- expanding `~'
/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.4/lib/rake.rb:2390:in
`expand_path'

Is there a way to run monit without it clearing env variables and resetting
$PATH?

Thank you!,
John
