Re: [Postgres-xc-developers] gtm output

[Nikhil S. <ni...@st...>]

Hi Michael,

I looked a bit more into this. Looks like either the gtm_ctl binary or the
gtm daemon invoked from it is not releasing stdout/stderr properly.

I worked around this by detaching to /dev/null by using the following
inside my script:

/usr/bin/gtm_ctl -D /var/lib/postgres-xc/gtm -Z gtm  start > /dev/null 2>&1

HTH,
Nikhils
