Hi,
I need some help with a memory leak running kannel. I'm using Debian (Etch)
on a Intel Core2Duo processor. I've tried the Debian-package and the latest
cvs-version on an x86_64 an i386 arch.
The problem is that the bearerbox runs into a memory leak when connected to
a Wavecom Dualband modem (WMOD2B-G900/1800). If I run the same system with
a Single Band Modem (WMO2-G900) everything is fine.
I've tested with several modems to exclude a modemfailure. Every test the
same result Single Band works, Dual Band doesn't. There are no warnings,
errors or panics in the kannel-core.log. bearerbox is connecting the modem
and sending messages correctly. Only thing is that after aprox 5 mins the
mainmemory and swap are full and the system isn't working anymore.
Has anyone any idea or solution for this problem.
