jtp10181 thanks for the example but i don't see any difference to my socket handling - it even uses the same timeout value
Hawk552 thanks for checking the code. i think my next steps will be to use the default timeout and if this doesn't help i will write a smaller proof-of-concept plugin. if this hangs the server as well then i will submit this to the bug section.
oh and dominion just pointed out that
this plugin hangs the server as well - i will check the code and see if it could be the same problem there.
EDIT:
the code is the same there, down to the timeout value. i will post there to see whether the author has heard of the same problems already.
