[rdiff-backup-users] Overflow errors

[Grigory Shamov]

Hi All,

I'm using rdiff-backup version 0.13.4 to backup /home directories to another
location on the same computer (say, /local/backup). For a first few months
everything had been OK, but the most recent two of three backup attempts are
ending with the "OverflowError: long int too large to convert to int"
messages from Python.

Just after this OverflowError the following message goes:

Exception zlib.error: 'Error -2 while flushing' in <bound method
GzipFile.__del__ of <gzip open file
'/local/backup/rdiff-backup-data/increments/ONE_OF_OUR_USERS/cvs/cvs/example
s/mytests/out.2004-09-14T05:07:00-05:00.diff.gz', mode 'wb' at 0x85c3560
0x85a556c>> ignored

The file mentioned is about 350 MB long -- I wonder whether errors could be
due to 2GB limit or something?

Could someone advice me, how to fix it?

I'm using RedHat9 Linux, kernel 2.4.20, and Python 2.2.

Thank you!
