[Twisted-Python] database threads dead

[Yun Mao]

Hi, I'm using twisted.enterprise.adbapi and postgres DB. Sometimes, the 
threads of adbapi just don't respond. There was no error reported as I 
insert stuff into the database, however nothing was inserted. I had to use 
kill  -9 to kill twistd process. However, the main thread was working 
properly. This happened randomly. Any clue?

2.6.10 kernel, ntpl enabled. thx
