Check Session check error

[JongBum Lee]

Dear All

My crowd will fail sometimes even though I am logged in with the correct id / pw login.

(/crowd/rest/usermanagement/1/session/session key ~)

The caller says that the login failed.

And when this happens, it always calls the procedure at the end.

After a long time to query cwd_user_attribute TABLE

(call sp_tables  ?, ?, ?, ?, ?)

'PROBABLYNOT', null, null, 'TABLE'

what does it mean?

(My Database is MS SQL)

However, after the occurrence of this phenomenon, the same ID / PW will be authenticated when logged in.
