"dewdrop would blow up my jackd"

That's troubling, especially considering that dewdrop consists of
client-only extensions and doesn't touch Jack.

There are no server plugins in dewdrop_lib.

Can you state any more specifics about this?

Hi James

I installed dewdrop and then played at a festival the next day. I was not
using any of the dewdrop ugens or classes. The festival had dicey power,
and Jackd blew up during sound check and again during the performance,
forcing me to restart. I did not get any error messages, but my cpu spiked
to 100% (at home in the studio, I hit 15 to 20% tops). Obviously this also
caused a horrible clicking. I removed the dewdrop quark and have not had
the problem since, although I'll reiterate that this may just be a
coincidence.

Tomorrow I'll reinstall and see if there are still issues, or if the power
spikes were what sunk the soundcard.

I see. I'm still going to go with "coincidence." Jackd is notably intolerant of power glitches in the audio card -- it has no recovery mechanism at all. I asked about that once on the Linux Audio Users mailing list once. I don't remember exactly what Paul Davis said, but as I recall, he was dismissive of the idea that any sort of fault-tolerance in this area would be desirable. So I abandoned the inquiry...

If the problem recurs with dewdrop, try installing individual components (using the quarks interface, to be sure dependencies are satisfied). If you can narrow it down to "I installed this one and the problem happened again, but I installed this other one and there was no problem," it would help to track down what might be going on.

It's been running off and on all day with no issues. I'm going to clear the
good name of the dewdrop library and say it was the power spikes that blew
up jackd.
