Hello,
I'm not able to see anything more on wireshark running on my laptop, and
I'm not able to run any tools on our target platform.
Yes, it looks like a deadlock problem. I haven't figured out why I only
get it for data sizes over one TCP frame size though.
For the moment I will have to leave this, but I will try to do some more
debugging later on. I'll try to use our "consol" for the LWIP_DEBUG
printouts, but it has some limitations.

That does indeed look odd. There are no further packets sent/received
on the connection after this point?
It looks like you've got some deadlocking issue perhaps, where the
second lwip_send call is sitting blocked trying to get a lock of some
kind (although lwip infamously has very few locks!) which isn't being
released by another thread.
I'm afraid that you'll have to do some debugging. If you can find out
where the blocked lwip_send call is waiting, that would probably help,
and try running the LWIP_DEBUG stuff on to get some more information
about what's going on.
