Now I have more data on this problem. The machine that is making
problems has 256MB RAM. I configured 2.5GB swap to get rid of the
problem, didn't help. Here is the log from last night:
2006-02-07 01:00:00 Running 8 BackupPC_nightly jobs from 4..7 (out of 0..15)

2006-02-07 01:00:08 Pool is 0.00GB, 0 files (0 repeated, 0 max chain, 0 max
links), 1 directories
2006-02-07 01:00:08 Cpool nightly clean removed 0 files of size 0.00GB

2006-02-07 01:00:09 Started full backup on tincan.4finger.net (pid=1795,
share=/)
2006-02-07 02:00:01 Next wakeup is 2006-02-08 01:00:00
2006-02-07 02:17:36 tincan.4finger.net: Out of memory!
2006-02-07 02:17:46 Backup failed on tincan.4finger.net (Child exited
prematurely)
The machine tincan.4finger.net has roundabout 30000 files, altogether
4GB. Another BackupPC with only 128MB RAM is backing up 5 Machines and
behaves very well. The biggest host to backup has 200000 files,
altogether 30GB of data to backup.
Any ideas?
ciao, Stefan.
