I'm afraid I can't help. If there is no error message, and if running the query in the mysql client works but via CQPweb doesn't, then I am utterly stumped, I'm afraid.
Just to check: you are still on 3.2.31,right?
Andrew.

Ah ... something more worth mentioning:
I do daily mysql dumps of the cqpweb database (for backup), and there was a remarkable growth of that dump yesterday:
-rw-rw-r-- 1 knappen knappen 5.5G Apr 25 01:07 cqpweb.dump
-rw-rw-r-- 1 knappen knappen 4.3G Apr 24 01:06 cqpweb.dump.bak
