[Jun 13 00:19:27 2001] Services terminating: Segmentation fault

 There were about 15 users in that #channel and all modes were successfully 
removed but services stopped after that. Is this normal (services flooded 
out?)?
 Last version (.19) on services and UltimateIRCd2.8.1 (client_flood is 
defined at 680, does this mean anything for services too?).
