[OLSR-users] olsr on arm9 system on chip from intersil isl3893

[ulf k]

hi everyone,
with some help from thomas last week at cbase, olsrd is now running on
isl3893 based wlan router.... but it seems that something is is not
running very well.
if the routing tables are very big, or some routing entries will be
deleted, the deamon runns out of memory.
for the first minutes everything is working fine like this:

you can see olsrd 233kb ...... 9844609!!
this will rise up to what ever and the respawnd is restarting the
appl. after crash.
sometimes its running for only a few min. sometimes its running the
whole night, depends how many links are established.

i can not find out exactly when that happens, any idea, what this could be?
