[SR-Users] Kamailio stability/timing problem w.r.t. registrations?

[Ovidiu Sas]

If you are running the stable version, there's need for heavy Makefile
patching in order to properly cross compile (not to include and link
to host libs).
The trunk has everything fixed and it's cross-compiling properly for
most of the modules.
Make sure that your binaries are properly cross compiled.

Depending on your ARM CPU, atomic locks may or may not work.
I tested openser without atomic locks (using regular locks) and it worked fine.

Ovidiu Sas
