Subject: Logfiles above 2G
There where days where harddisk had a limit of 2GB or 4GB
There where days where partitions had a limit of 2GB or 4GB
There where days where files had a limit of 2GB or 4GB
Those days are long long gone.
However if kannel's gwlib runs in full debug mode and the logfile hits
2GB, the application quits/stops working and when you relaunch it, it appends
to the same 2GB logfile and quits again because it cant go beyond this 2GB
limit.
Now this is not a bug of Kannel but one of the operating system.
This bug doesn't exist under MacOS X but it does exist in Linux Fedora 5 with
a ext3 filesystem. From reading log.c, I can see that kannel does
fopen("filename","a") and then vsfprintf or fprintf. As the file is opened
append only, no seeks are used or anything fancy, I can not understand why the
file is limited to 2GB even thought the filesystem for sure can handle files
larger than 2GB.
On our system it takes 2-3 days to hit this problem with a empty log
file. As we mainly use MacOS X we never see this problem but having added a
new Linux machine to the park, I'm puzzled to see this problem I've already
spotted in 2001 and would have expected to have been long fixed in current
linux kernels.
Anyone have a hint here?
