Process being restarted by monit validate even if it is running

Hi,

I have a process which I am monitoring with following rules

check process v2api with pidfile /var/run/node/v2.pid

start program = "/usr/local/bin/nodeinit v2 start"

as uid root

stop program = "/usr/local/bin/nodeinit v2 stop"

as uid root

if failed host 127.0.0.1 port 10400 protocol http

request /api/v2/ping

with timeout 10 seconds

then restart

if 5 restarts within 10 cycles then alert

Before running monit validate, I checked the pidfile of the process

# grep [0-9]* /var/run/node/

/var/run/node/v2.pid:31566

# cat /var/run/node/v2.pid

31566

I also verified with ps on the process id

# ps aux | grep 31566

root 31566 0.3 1.7 605684 29820 ? Sl 05:24 0:01 /usr/local/bin/node /usr/local/share/nodeapis/server.js

Now when I run

# monit validate --verbose

'v2api' Error testing process id [31566] -- No such process

'v2api' process is not running

Does not exist notification is sent to address@hidden

'v2api' trying to restart

'v2api' stop: /usr/local/bin/nodeinit

'v2api' Error testing process id [31566] -- No such process

/usr/local/bin/nodeinit: line 80: kill: (31566) - No such process

Killed v2 process with pid 31566

monit: pidfile '/var/run/node/v2.pid' does not exist

'v2api' start: /usr/local/bin/nodeinit

monit: pidfile '/var/run/node/v2.pid' does not exist

v2 has started with PID: 1150

It complains that the process is not running.

I am using the development version of monit that Martin linked to a couple of days back, with websocket support.

# monit --version

This is Monit version 5.8
