Thomas,
I've installed a standard jessie/amd64 installation running the same

Can you provide a reproducible case? e.g., does this happen on the first
authentication attempt after starting saslauthd (with the shadow backend),
or are there other factors at play that you can identify?

It does not seem that debug gives out any interesting information. Here are
the last lines from when the child processes died:
