Do you have any idea what could be done about this?

Package: dnrd
Version: 2.7-1
Severity: important

At least once a day, dnrd will eat up all available CPU cycles, and refuse
to resolve anything. "/etc/init.d/dnrd stop" says that dnrd is not
currently running. Killing it by hand and restarting it with
"/etc/init.d/dnrd start" solves the problem for a few hours.

So far, I have been unable to find a clue as to what causes this
behavior, and I have noticed no discernable pattern on these failures.


-- System Information
Debian Release: 2.2
Kernel Version: Linux mysidia 2.2.17 #5 Fri Nov 3 02:56:06 EST 2000 i486 unknown

Versions of the packages dnrd depends on:
ii libc6 2.1.3-10 GNU C Library: Shared libraries and Timezone

Thanks

I have never observed this behavior. I would suggest compiling dnrd with debugging (-g) turned on, and the next time it happens attach gdb to it (gdb dnrd...

... I never tried to debug a running program before; guess it's time I learned something new. :) My original plan was to run it in foreground (with -d), kill...
