Question

What does the error message remote delivery process count got out of step mean?

Answer

Exim uses subprocesses for remote deliveries; this error means that the master process expected to have a child process running, but found there were none. Prior to release 4.11, this error could be caused by running Exim under strace on a Linux system, because stracing causes children to be stolen such that a parent that tries to wait for any of my children > is told that it has none. Current releases of Exim have code to get

round this problem.
