The 2gb limit is in 32-bit cpu: Most exactly in libc, kernel fs
drivers and VFS layer.

The limit exists because linux ports for 32bits CPUs use 32-bit
integers for file access and locking, so: 2^31 - 1 = 2GB

My solutions are:
1) You can implement LFS
2) Use XFS
3) Logrotate

- logrotate is your friend... :)
- or use 64 bits arch

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?
