MySQL not returning successful results on statement - query looks like it's hanging but is successful So we have a script(s) that runs in succession. 
Randomly this task would halt/freeze and error out simply because it did not see a returned response from the MySQL server saying the statement ran fine breaking the entire procedure.
However when manually checking against the DB, the statements all ran fine it's just the script (using JBDC) aborted since it didn't see a response.

Nothing in the error logs, etc.

Is there a setting or reason why MySQL would be doing this?
This is version 5.1 .

I thought of network issues causing this but this seems to happen in 2 different environments, both through a WAN and local LAN .

any ideas?
You can try setting up a shell script that runs the SQL scripts or write a program in perl/whatever language which tries to log the errors and return codes from MySQL. Otherwise it is very difficult to troubleshoot without knowing the errors.

You could also add SHOW ERRORS; and SHOW WARNINGS; to your SQL scripts, but I suspect the problem is not with your queries.
