Block on anything else (like on getting some resource it needs to deal with the client provided data, like an output pipe)?

You just have to give a lot more information.

Otherwise tcpdump, various system call tracers (like Astrid hinted about), potential libcall tracers (like ltrace) and
Since you are writing your own server, a debugger like gdb, are your friend.
