Unable to delete some user accounts

[gbosch]

Hello,

I was trying to delete all user accounts and I met with these 2 problems on 2 different users:

user 84 in context 1 could not be deleted: 
Server response:
 com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`oxdatabase_8/messagingAccount`, CONSTRAINT `messagingAccount_ibfk_1` FOREIGN KEY (`cid`, `user`) REFERENCES `user` (`cid`, `id`))


user agenda in context 1 could not be deleted: 
Server response:
 FLS-0017 Category=5 Message=File does not exist in filestore "/opt/filestores/fs1/1_ctx_store/00/00/05". Consider running consistency tool. exceptionID=-1610095415-3296

I reported the first one was subscribed to a Twitter account, and I was not able to delete it since the user removed the subscription. Is not possible to force user deletion and all tables referred to?

With the second one, I don't know what is the problem.... What consistency tool should I consider to run? As the error tells, this file not exists in infostore folder :S

Thanks,
Gerard.
