<font size="+1">Hoping someone can help me figure out what's causing X
runs at precisely 10 minute intervals - not 9:59, not 10:01 but exactly
10 mins.<br>
<br>
My setup: <br>
<br>
AMD 64 X2<br>
Feisty<br>
2 GB DDR2 800 mhz<br>
M-Audio Firewire Solo using Freebob<br>
Sample rate: 96,000<br>
Periods: 3<br>
Frames: 64<br>
Latency: 2 ms<br>
Realtime checked in Qjackctl<br>
Priority = 89<br>
Qjackctl 0.2.21<br>
<br>
# ps -C jackd -cmL <br>
shows:<br>

As I understand it, the FF indicates realtime.<br>

Messages from JACK:<br>

<br>
Note that in the first instance it's an underrun; 2nd instance an
overrun, which seems odd to me (ie I'd think with the X runs happening
on such a precise schedule it would show the same problem each time).<br>
<br>
I've tried using System Manager to track down any processes which might
be scheduled to run every 10 mins and can't pin down anything. I also
tried stopping ntpd but the problem continued.<br>
<br>
Other programs which run simultaneously:<br>
<br>
- Beryl<br>
- Mythtv backend<br>
<br>
Using Ardour neither increases the X runs nor eliminates them - they
still pop up at 10 min intervals.<br>
<br>
Any ideas or suggestions? Could Freebob be the problem? Are there
system processes known to run at 10 min intervals that could be
interfering?<br>
<br>
Also, not sure this has anything whatsoever to do with my X runs, but
Qjackctl also reports a whole series of:<br>
<br>
QTextCursor::gotoParagraph Index: 49 out of range<br>
load = 4.1724 max usecs: 26.000, spare = 640.000<br>
load = 4.0381 max usecs: 26.000, spare = 640.000<br>
load = 3.9710 max usecs: 26.000, spare = 640.000<br>
QTextCursor::gotoParagraph Index: 49 out of range<br>
QTextCursor::gotoParagraph Index: 49 out of range<br>
<br>
I also tried running JACK from console, with the same results.<br>
<br>
Driving me nuts as every time I need to do a take, I have to wait until
an X run hits, then I have a 10 min window to record, which leaves me
thinking about the impending X run, rather than the part I'm playing!<br>
<br>
Many thanks!<br>
