there has been discussion at [903] about enlarging the network buffer to 
the maximum possible frame size for UDP packages.

right now that size is rather small (4096 bytes), which is usually 
enough for real networked traffic (as most networking components will 
impose a default maximum package size of 1500 bytes), but when the 
computer is "networking" with itself (communicating via "localhost") 
that limit can be easily blown.

until the corresponding PR [1122] is accepted (and there is a bit of 
reluctance accepting it), the only viable workaround is by not sending 
large packets (that is: instruct your sending application to not send 
packages that exceed the 4096 byte limit)

in the meantime, add your mojo to the PR resp issue.
