I am running an apache httpd server, v2.2. It has been working for some time, but since the last restart (the VM had to be restarted), connections (for example from the same machine with
wget) to it simply time out.
netstat -tulpn has shown the process is listening on port 443 as expected. The logs do not show anything (although I have set the LogLevel to
debug). Also I noticed that many zombie processes are spawned and killed again -- always 1 to 5 "defunct" processes are shown when I do
ps -elf | grep http.
Any ideas about what may cause this? The configuration has not changed.
