Re: [Wrapper-user] pid file not working???

[Leif M. <le...@ta...>]

Dean,
We have been looking into this and it turns out that this is a bug
introduced in version 3.3.7.   We added a new WRAPPER_PID environment
variable that can be referenced in the wrapper.conf file for things
like log files, etc.   The problem is that the PID was being set
before the process was daemonized (forked).

This is a bug if you call "wrapper.sh start".  It is working fine as
"wrapper.sh console".

We view this as 3.3.7 being pretty much broken for UNIX platforms and
will be doing a 3.3.8 release with this fix within the next couple
days.

Sorry for the trouble.

Cheers,
Leif
