[PlanetCCRMA] CRON - cannot connect to jack server - 2 minutes after the hour

[Mark Knecht]

Hi,
   Late breaking news. After seeing jack fail twice at 2 minutes past the
hour, I just turned off crond at 4:30PM for the evening. The machine then
went past 5PM and jack_lsp did not have any problems communicating with
jack. I left jack running and will check it again in the morning to see if
that fixes it.

   If so, I'll probably need a bit of guidance about how cron runs and how
to modify what it does. Thanks to everyone who's made comments.

Cheers,
Mark

Hi,
   Following on, I do think this is cron related. Jack was stable right up
to the hour, then I sat and watched it each 30 seconds or so. Jack failed
again at just around 2 minutes after the hour, just like last time. The
processes are still there, and they even generate an occasional xrun
message, so the server is alive, but NONE of my jack applications can
connect to the server anymore.

   I need to understand the cron process.

   However, why should jack become completely isolated??? This seems very
strange indeed!!

   Ideas warmly welcomed.

Cheers,
Mark
