ULOGD: Log file size limitation?

ULOGD: Log file size limitation?

[dstorvik]

I have ulogd running to track netfilter nat connections.  When my log file reaches 2147483647, exactly 2 gb it stops writing with no errors or warnings.  It then picks back up when logrotate rotates the file and kicks ulogd.  I am rotating daily so other than rotating on an intraday period, which I'd rather not do, I'm not sure what to do.   The file system is a Logical volume group with EXT3 filesystem, and I believe 1K blocks which should lead to a maximum file size of 16 Gigabytes from what I understood. Is that not true and I simply have a file system problem or is this some limitation or bug in ULogd?

Thanks
   Derek

This is quiet strange because AC_SYS_LARGEFILE is put in ulogd2
configure.ac.

Has autoconf put in your config.h :

    /* Number of bits in a file offset, on hosts where this is settable. */
    #define _FILE_OFFSET_BITS 64

That is exactly what is in my config.h file

/* Number of bits in a file offset, on hosts where this is settable. */
#define _FILE_OFFSET_BITS 64

Should that be uncommented and recompiled?

Thanks
