Any help?

[Adam]

Looks like something caused by db_sql_live_read. I don't have time now to look but if you unload that it should be ok.

[Jens Voss]

1. a "/nickserv identify" caused the db_mysql_live_read module to search the mysql database for the nick
2. the nick was not found in the database, so the db module deleted/dropped the nickalias (thats not a bug)
3. because the nickgroup has only one nickalias, the nickcore was also deleted/dropped.
4. anope crashed while deleting the nickcore. this seems to be bug.

What anope version are you running? Its not the 1.9.6 release, but its also not the current git, because the line numbers are not matching ...
