physical machine is the same? Is it standard OS installation, or some customizations (e.g. custom kernel modules, etc.)? Embedded device? What CPU?

What are the differences between the server that works and the one that doesn't? I mean hardware and operating system details?

Checking quickly the source code and comparing with logs, it doesn't reveal any problem -- it is about allocation of the next fragment, which was not used at all before, after the one allocated previously. The only reason I can think of it right now is corrupted memory or faulty OS.

Are you using 4.1 or 4.2?

Because the subject mentioned 4.2 but the version of kamailio is 4.1
