Here we are, but the log is in French (sorry for that):

In short, this is today's log, so it's an incremental backup. Everything
went well except some md5sums are missing.
The master's backup (from 2011/03/01) still hasn't been sent, it's still
working on the md5sums. Here's what htop says:

gzip and md5sum are mostly in D state, but their CPU time is progressing
slowly so I guess they reach R state sometimes.
So what happens seems clear: the lock is taken during the backup, but
released before calculating the md5sums. And in my case the sums take a
long time to compute, so the next backup comes before the previous sums
are there => error message in the log.
