Crowd sync sql error: CROWD207.SYS_C0020403 after upgrade

[David Forsman]

After upgrading Crowd 2.0.7 to 2.5.1 yesterday I've seen a SQL error a couple times in atlassian-crowd.log. See attached stack trace. (actually seen it twice, ~24hrs between.)

Looks like a uniqe constraint violation in table cwd_token.

Can this be fixed easily in a nice way?

(Or hacker-style: Stop crowd & clear table?)

(crowdStack.txt)

Otherwise Crowd seems to be working fine after the upgrade. But it would be nice to not have this error in logfile.

I would suggest the SQL approach, unless you can find the row in question that is causing the violation, and removing just that record.

Removing all tokens would logout all sessions for all users + applications currently using Crowd for authentication.
