OK, I restarted dovecot with

as you suggested. My dovecot-auth process just quit:
Jul 11 17:50:33 helium dovecot: auth(default):
worker-server(andrex,127.0.0.1): Aborted: Worker process died
unexpectedly
Jul 11 17:50:33 helium dovecot: child 14415 (auth-worker) returned
error 1
but this time with signal 1, apparently because valgrind wasn't able
to
allocate any more memory. The valgrind log is below.
auth_process_size = 0 helps with this.

Hmm. A bit strange if the error is coming from dlclose().. That would
point to a bug in libc.
