I mean what exactly are you doing and what step fails? is the malloc not working? or ? When I use B2B, I have to forward my INVITE in another process, that is why I have to copy it (body, URIs, ...) in my shm_malloced internal data structure. It works, but I find it ugly. Moreover, sometimes I get an internal error because I don't have enough shared memory, that's why I want to find a better way. I'm blocked by OpenSIPs' architecture. If this is the only way, I could optimize it on my side. Do you know actually, how much percent of the 32 MB of shared memory, is used by OpenSIPs ?
