Bug#1012431: exim4: Exim does not deliver local mail immediately through pipe transport

[Kamil Jońca]

It seems that there is some relation about process limits
When I changed in limits.conf

--8<---------------cut here---------------start------------->8---
grep logcheck /etc/security/limits.conf              
logcheck        - nproc 5000 
--8<---------------cut here---------------end--------------->8---

exim starts deliver mail immediately.
On the other hand when I restore default limits:

--8<---------------cut here---------------start------------->8---
echo bla |sudo -u logcheck mail frane
--8<---------------cut here---------------end--------------->8---
the difference is that
"kjonca" have a lot existing processes on this machine (and limts also
set higher than usual) and franek logging in occasionally.
So it seem that tere is relation between process limits sender and
recipients.
