I'm having an issue with anope always panicking when certain users modify their nickserv access list, and it doesn't matter what the mask that's added is: services always panics when the user or users add them. I have had the problem with two users total, ever, though only one currently has the issue. I believe it may be something to do with the user's flags, as other users can modify their access list without incident. The user currently having the issue has a flags/options mask of '1521'.
I've never had this problem when not using MySQL. I would also think it prudent to mention that I do in fact make use of the RDB functionality of anope and run a cronjob every four hours to import users from the services' registration website. Also, to preempt any os_raw superstition: I have DisableRaw enabled in services.conf.
I was wondering if anyone else had an issue similar to this and if so, what they did to rectify the issue. As of right now, I'm leaving the ns_access module unloaded to prevent the users that are able to freeze services from doing so. Clearly this is a less than ideal solution, so I'd really appreciate any help.
