Hi,
Running dovecot 2.2.27 (c0f36b0) on Debian GNU/Linux stable (version 9.6), I'm trying to use the execute command in a sieve script, with direct execution (not service socket).
The script is executed, and returns (the process exits), but the dovecot-lda process seems to not notice, and thinks the script did not terminate. After sieve_execute_exec_timeout has passed, it sends a TERM, a bit later a KILL and then logs a failure.
The "ps -Af f" looks like: S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB S 0:00 \_ /usr/lib/dovecot/dovecot-lda -f master@blitz.conuropsis.org Z 0:00 | \_ [foofilter] <defunct> S 0:00 \_ /usr/sbin/exim4 -Mc 1gMazS-0007IV-RB
The dovecot debug log looks like:
lda(user): Debug: Loading modules from directory: /usr/lib/dovecot/modules

and an strace on the dovecot-lda process shows it is in an "epoll_wait(9 ....".
The script is very simple:
#! /bin/sh
cat > /dev/null exit 1
Anyone has a clue? Thanks in advance.
