This SZ_GetSpace: Overflow on netchan->message You can experience when too many messages are generated in some permissible time. Many times this error is generated with some motd at client_connect (some welcome messages). Maybe try to do shorter this motd file. If You have some plugin in adminmod controlling antiflood protection, try to disable it or change the settings for it and look if this problem still happen at Your server. But maybe first test You need to do it's this - disable adminmod (only Your favourite bot loaded) and see if the problem still exists. You can also try to disable botchatting (if this bot has something like this).
