After examining this issue a bit more, I'm even more confused.
Findings:
* When changing the memory manager to qm, Kamailio starts. Tried 3 times with fm, 3 times with qm, had three failures and three successes.
* When running with fm memory manager, I can get it running by adding these lines basically somewhere in the main route:
if (is_method("INVITE")) { xlog("L_INFO", "Hello World\n"); }
Again: Tried it three times.
Do you have any idea on how to debug this any further? I'm all out of ideas. And it was running without problems under 4.3.
I do have two strace outputs from a successful and a failed start, which I could send you if you want to look into this.
