Mod_jk.log grow up

[poheng]

Hi,
I hope i post on the right forum.
Well i expose my problem.
My mod_jk.log represente 15 go. And he go on to grow up.
Can i delete this file and recreate ?
Or can i configure jk module to delete log file 1 time per week?
Is it possible to manage jk log file, because this mornind my sys volume was full?
