Thanks for posting your issue. It helped assure me of my sanity when I got nearly the same thing. In my case it's coming during an install of JasperReports Server.

[advanced-sql] Failed to execute: alter table JIDomainDatasourceDSRef add index FKFDA42FC7106B699 (ref_id), add constraint FKFDA42FC7106B699 foreign key (ref_id) references JIResource (id)
[advanced-sql] com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Duplicate key name 'FKFDA42FC7106B699'

After getting this error while executing a large SQL script, I can successfully run the exact same alter table statement manually. I cannot figure out why MySQL occasionally rejects some alter table statements. Restarting MySQL indeed solves the problem [for an unspecified but temporary time period].

I'm using exactly the same build of MySQL on Mac OS. We could optimistically hope that this is a MySQL problem limited to version 5.1.48 and/or limited to Mac OS… but I would feel a lot more comfortable if I could track down a bug report in the MySQL tracker.

If any MySQL gurus come across this thread… I love an opinion on what is causing this problem.

Matt
