Unable to rsync files of size 30 GB

[Nitin Agarwal]

Hi,
I m using rsync on AIX 4.3 for backing up a huge database. Rsync gives error on bringing files
greater than 2 GB. I tried the 64 bit version of Rsync 2.5.6 (on 64bit file system) also, but it
didnt worked.

Command i m giving is:
rsync -avz --ignore-errors 10.10.10.10::backup /backupdir

OUTPUT IS AS FOLLOWS (with error message)
receiving file list ... done
./
1
ABC.0.db2abc.NODE0000.CATN0000.20031012072506.001
write failed on ABC.0.db2abc.NODE0000.CATN0000.20031012072506.001 : Error 0
rsync error: error in file IO (code 11) at receiver.c(243)
rsync: connection unexpectedly closed (182 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)

I repeated command 2-3 times (to check for any network errors) and it always gave the error after
bringing approximately 2 GB of data.
The file size is 13GB.

Machines on which i m running this command are RS 6000 with PowerPC Power 3 processors (4 CPU @ 350
MHz each) Memory is 2.5 GB (approx,.)

Please help
Thanks in advance
