logging breakdown

[Marek Augustyn]

Hello,

I'm getting strange exception raised using module logging.
It's strange because it happens only sometimes, and it happens
in different places (but always in a logging method).
i.e. this line of code:

log.info('SMS sent')

produces following traceback:

Traceback (most recent call last):
File "L:\_progs\pyth on\test\send_sm s.py", line 36, in send_sms
log.info('SMS sent')
File "L:\Python23\li b\logging\__ini t__.py", line 893, in info

File "L:\Python23\li b\traceback.py" , line 69, in print_tb
if line: _print(file, ' ' + line.strip())
File "L:\Python23\li b\traceback.py" , line 13, in _print
file.write(str+ terminator)
IOError: [Errno 9] Bad file descriptor


This is the way I initialize logging:

def initLogger(file name):
log = logging.getLogg er('test')
formatter = logging.Formatt er('%(asctime)s %(name)s %(levelname)s %(message)s')

# file
hdlr = logging.FileHan dler(filename)
hdlr.setFormatt er(formatter)
log.addHandler( hdlr)

# screen
hdlr = logging.StreamH andler(sys.stdo ut)
hdlr.setFormatt er(formatter)
log.addHandler( hdlr)

log.setLevel(lo gging.DEBUG)

return log

log = initLogger('tes t.log')

I pass variable "log" to functions requesting it.
My script runs continually, sleeping 1h, doing something, sleeping 1h, etc.
Is it possible that file handler expires or something?

Do I do something wrong?

Thanks,
