Hi all,
I have a daily backup script where I backup a database and later in the
process, compress the backup files using
for i in /home/tmp/*dbk
do
j=${i##/home/tmp/}.gz
gzip -v < ${i} > /home/public/backup/stage/${j}
done
This usually works just fine (the compressed files are getting created
in a different filesystem from the uncompressed backup files). But every
few days, gzip crashes during the process and I get this output in the
email cron sends:
73.6%
72.8%
72.6%
73.0%
72.5%
/home/root/bin/backup: line 32: 27749 Segmentation fault gzip -v

Has anybody seen this before? As you can see, 7 of the files are getting
compressed just fine, one doesn't want to. It still outputs the
compression percentage (42.4%) - but the output file is garbage:
gunzip < phone-6-20041219.odbk.gz > /tmp/x.odbk
gunzip: stdin: unexpected end of file
Each of the input files (except the last one) is 2 GB (minus 1 byte) in
size.
Machine specs: FC2 with all the latest updates, X not running on the
console, AMD 3200+ CPU, 1.5 GB memory, ASUS motherboard
Any help would be appreciated.
How big is the the source file you are trying to compress?
