Using Teiid Designer 11.1 version (did not test older versions), during the import process using the Teiid Connection importer, if you change the default timeout property from 120 to any value (on the advanced tab) from there on any teiid connection importer deployments will fail with timeout. Even setting back to 120 will not work.

I feel the code somewhere may be interpreting the value as milliseconds instead of seconds.
