Re: log files rotation

Thanks for your answers.
Actually, I'm not sure about the log file thing.
Thing is, for the past few days, mathopd stopped working in the 11pm-ish 
hours (not serving requests anymore).
The fact that it started working again at 12pm (date of the log file 
rotation) had me loook at the log files, and they were all of size
2147483647 (which is ~2 gigs, not all that big), so i extrapolated (maybe i 
was wrong) that it could be the file max size that was reached.
I'm running on a kernel 2.4 on a RH7.2 (yeah i know) and i beleive the FS is 
ext2 (maybe there's a lower limit for this type of file system ?). 

Thanks anyway :-)
