"Resource temporarily unavailable" means a "send" to the TCP/IP socket has blocked but you have a non-blocking socket.

It is normal to have non-blocking sockets (in this sort of situation), so the bug is that the server is not detecting the "would block" error return and simply queuing up the write to be done later.

is there any way to go around it or some way to keep people from getting spammed off?

Yes there is a way around it. Fix the bug.

You haven't said what code exactly your friend is using - is it stock ROM? Or has s/he added something?

I don't recall complaints of this nature about stock ROM, but may be wrong.

Possibly if someone added "an extra message" without understanding sockets programming they might easily cause this problem.

Failing that, you have a clue *where* it is happening, the message "write_to_descriptor" would be found in the code (maybe more than once). If more than once, make them unique (eq. "write_to_descriptor_1") and so on, and then when you work out which one it is, look closely at the error check directly after the write.

his mud is a highly modded rot mud but i have a copy of stock rot that has the same bug in it.. ill try to narrow it down more though
