Hi, I am using our modem bank with four SIM cards and send 1000 per SIM card and ofono is segfaulting in the process of doing so. The crash appears to be due a memory corruption and I wonder if you have experience in debugging those. This is ofono-1.11 with some patches to build on debian stable. kind regards holger gdb backtrace: #0 0xb7e51c02 in dbus_connection_get_dispatch_status () from /lib/i386-linux-gnu/libdbus-1.so.3 #1 0x08054be6 in watch_func (chan=0x8712e78, cond=0, data=0x8713590) at gdbus/mainloop.c:105 #2 0xb7f1b6fe in ??
