Re: Logfiles above 2G

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
