Comment # 3 on bug 908782 from Fulvio Malfatto

Added info:
Segfaults seem to be related with the presence of
 KeepAlive On
in server-tuning.conf

Tried with KeepAlive Off and it worked several hour without any segfault.

Now I'm trying to change limits for processes and keepalive:

KeepAlive On

MaxKeepAliveRequests 64
#MaxKeepAliveRequests 100
#MaxKeepAliveRequests 256

KeepAliveTimeout 3
#KeepAliveTimeout 10

        ServerLimit        300
#       ServerLimit        256
        MaxClients         300
#       MaxClients         256
