Sending mails to lists with more than about 15 subscribers produced this sort of bounce:
email@example.com Child process of eoc_transport transport (running command "/usr/bin/enemies-of-carlotta --smtp-server=localhost --incoming") was terminated by signal 9 (Killed)
I found the cause. The transport responsible for running the pipe had max_output set too low. So I increased it. (I could instead stop the script producing so much output...)
A better fix is not to increase max_output, but rather to call EoC with the "--quiet" flag, so it doesn't produce any output at all. Then Exim's log_fail_output and return_fail_output options become more useful too.
