guv daemon died

[randomsock]

Just starting an app in the UI and it lost contact with guv-web. When I checked my terminal, the whole guv daemon had gone.

This was the last entry in /var/log/guvnor/guvnor.error.log (pretty printed):

v3.5.7 btw

[randomsock]

Seems solid, every time I tried to start an app from the UI. Same app will start ok from the command line.

I've completely cleared down everything I can think of:

[root ~]# guv kill
[root ~]# npm remove -g guvnor
unbuild guvnor@3.5.7
[root ~]# rm -f /etc/guvnor/apps.json
[root ~]# rm -f /etc/guvnor/processes.json
[root ~]# rm -rf /usr/local/guvnor/*
[root ~]# ps -efH | grep guv
root     27803 27592  0 21:56 pts/2    00:00:00                 grep guv
[root ~]# npm install -g guvnor --unsafe-perm
...
[root ~]# guv
No running processes
[root ~]# guv --version
3.5.7

Then started guv web from my own user, installed an app with the UI, tried to start it and guv daemon dies. Weird that the same works fine from the console, so at least it's not a blocker at the moment.

Not quite sure what could cause this, I've released a new version that wraps the dnode invocation in a try/catch block so it should at least stop the daemon process from crashing while I dig a little deeper.
