Will try, but result is likely to be inconclusive as I have no way of generating the offending messages - if no lockup happens after enabling checks, it could be that the option helped, but also that no lockup-inducing messages were received.

Please add "--enable-checks" to ./configure options, does this solve the problem?

from irc:
<Guy-> spiralvoice: I think I'm hitting a bug in mldonkey-server 3.1.0
<Guy-> spiralvoice: after a (very short) while it just stops doing anything
<Guy-> the last log message (after turning up verbosity a great deal) is:
<Guy-> [KAD] Error Invalid_argument("index out of bounds") in udp_handler, dump of packet:
<Guy-> I'll pastebin it
<Guy-> spiralvoice: http://pastebin.com/WDrgud9j
<Guy-> at this point, no further messages are logged, there is no outgoing network traffic, gui connections time out
<Guy-> http connections too
<Guy-> spiralvoice: disabling kademlia seems to avoid it, so apparently the message is related to the problem
