Q0046

Question

A short time after I start Exim I see a defunct zombie process. What is causing this?

Answer

Your system must be lightly loaded as far as mail is concerned. The daemon sets off a queue runner process when it is started, but it only tidies up completed child processes when it wakes up for some other reason. When there's nothing much going on, you occasionally see defunct processes like this waiting to be dealt with. This is perfectly normal.
