Hi,
I'm using experimental batmand Rev 756. After a while the batmand is crashing. with "Segmentation fault". the crashing batmand is running on i386 (debian 2.6.22.1). All routers are running the same batmand version. I have not checked if also the batmand crashs on the routers.
syslog: batmand[6733]: Error - got packet from unknown client: 10.12.10.17 (virtual ip 169.254.1.1) batman log (-d4): Error - SIGSEGV received, trying to clean up ...

Just to be sure, Where does it show Rev 756 ? Because this reveision has never been committed for batmand-exp. Do you mean rv752 ? Have you experienced this with previous revisions?

can you check that? To be honest, I am usually not testing it a lot on i386. I'll do so now. But on the mipsel devices which Iam mostly using for testing it runs since weeks without problems.

can you send me that batman-crash file, and even better also a core dump? (if its to large send it private).
thanks, axel
