Indeed.
See my analysis there:
http://www.atari-forum.com/viewtopic.php?p=257629#p257629

I suspect it is related to the gethostbyname() bug.

Markus has judiciously noticed that all the problematic software usereception of UDP packets.

Since this problem only affects mintv4e.prg, I have a big suspicionabout the UDP checksum routines. They are written in assembler, and theywere tricky to convert to ColdFire (lack of ROL/ROR instructions, etc.).

We should start by adding (or enabling) debug trace on the reception ofUDP packets, to see what's happening.

Also, since we experience huge timeouts, we should determine what thekernel is doing during that time.
