Hi! Is there any known memory (leak) problem with BackupPC 3.2.1 and rsync backups?
I upgraded our Debian host with the latest wheezy backuppc package (3.2.1-2) and suddenly encounter "out of memory" problems with a particular share. The problem occurs with a dump of a remote Linux system via rsync. Watching the BackupPC_dump process via 'top' shows that it constantly grows in size until it consumes roughly 1.5G memory until it suddenly terminates. Despite the reported "Out of memory" error (see log below), the system is not reaching exhaustion - at least what I can see within top (host has 3GB RAM and swap is not growing over 10% (of 1GB)). Invoking the dump manually with BackupPC_dump -i -vv nfsserv shows this (truncated) log: [...] CheckHostAlive: returning 0.088 incr backup started back to 2012-04-10 21:55:42 (backup #333) for directory /export/share started incr dump, share=/export/share Running: /usr/bin/ssh -q -x nfsserv sudo /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --one-file-system --checksum-seed=32761 . /export/share/ Xfer PIDs are now 17175 xferPids 17175 Rsync command pid is 17175 Fetching remote protocol Got remote protocol 30 Negotiated protocol version 28 Checksum caching enabled (checksumSeed = 32761) Got checksumSeed 0x7ff9 Sent exclude: /tmp Sent exclude: core Got file (0 of 149): .
