Okay cron spawns cron to do things, so 30 copies with 30 copies of qrunner is probably qrunner not finishing fast enough. > It all started with that Mozilla spell-check error and ever since, whether > mozilla is running or not, I suddenly find that the machine won't respond to > the mouse, keyboard or network for upto TWENTY minutes at a time. What error? Sounds like typical excess load, I assume you could drop priority of cron jobs, perhaps limit resources to any problematic programs - users. > WHAT is wrong with it? I get nasty problems if Demon serve up too much spam all at once, as it spools too many Python jobs to sort the wheat from the chaff. Can you wrap qrunner not to run if it is already running? i.e. Something like - and I haven't tested it. mv qrunner qrunner.real vi qrunner RUNNING =`ps -ef | grep qrunner.real | grep -v grep | wc -l` if [[ RUNNING -eq 0 ]] then qrunner.real fi > I've tried stopping crond before starting any work, but now even KPPP causes > the system to loop. I'm beginning to think it's the linmodem driver. Possible hardware issues as well - but the cron thing sounds just like overwork. Did you change any hardware or kernel settings? > BTW.

Too much noise to work - how much more detail do you need ;-( BT can measure line gain issues automatically from the exchange - - some voodoo in modern exchanges. If it is intermittent I'd start with cabling your end, and try a different modem (or check if you have too many phones/answer phones plugged in - that kind of stuff). BT can be good on modems, but I think you are only garanteed 9600 baud under the USO. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE+QGAMGFXfHI9FVgYRAg53AJ4/vVEkxa/XFSylY3Mr9La1DJXKjwCgrpzG xIEweDdgiSfyNBT/f+NNG64= =6t8l -----END PGP SIGNATURE----- -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
