[OLSR-users] Assertion `metric_counter' failed

[Philippe Vanhaesendonck]

Hi!

We are running OLSR 0.4.9 on roughly 25 nodes in the Brussels area.

On one node, olsrd aborts on a regular base with the following message:
olsrd: src/process_routes.c: 318: olsr_delete_routes_from_kernel:
Assertion `metric_counter' failed.

Some facts:

    * I have not seen this on any other nodes (but we are only running
      OLSR since a couple of days)
    * The machine is an i386 BusyBox / uClibc base (Elan SC-400 processor)
    * It runs from a couple of minutes up to a couple of hours
    * We are using NLQ -- all nodes share the same config file
    * The routing is not stable -- that is it changes very fast. When
      you run olsr in debug mode (-d 1), it will scroll at high speed.
      This is probably due to the quality of the links, but we have
      substential number of changes in the routes)

Hereunder the config file, a capture of the problem and a dot-draw of
the topology (the node having problem is bulles.bxl.rc)

Any idea / suggestions?

thank you in advance
