I am trying to figure out what causes this extra delay during these hours but i cannot find anything. I tried to check the crons to see if there is something automatic that runs during these hours that is causing the delay but i dont think my answer is there.
What makes you think the answer is not in the crontabs? (The question is meant serious, what haveyou done to come to that conclusion?)
You might want to start with the basic tool for all things performance: vmstat. Use
Code:
vmstat -tw 1 | tee -a /some/log/file
and analyse the log. See if there is any significant difference between the first 5-6 minutes of an hour and the rest of the time. See if there is a difference between the first 5-6 minutes of the hour on server3 and the other two servers.

rotatelogs(8) System Manager's Manual rotatelogs(8)NAME
rotatelogs - rotate Apache logs without having to kill the server
SYNOPSIS
rotatelogs logfile rotationtime [offset]
DESCRIPTION
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature, which can be used like this:
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
This creates the files /var/logs/logfile.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a
multiple of the rotation time, so you can synchronize cron scripts with it). At the end of each rotation time (here after 24 hours) a new
log is started.
OPTIONS
logfile
The path plus basename of the logfile. If logfile includes any Otherwise, the suffix .nnnnnnnnnn is automatically added and is the
time in seconds. Both formats compute the start time from the beginning of the current period.
rotationtime
The rotation time in seconds.
offset The number of minutes offset from UTC. If omitted, zero is assumed and UTC is used. For example, to use local time in the zone UTC
-5 hours, specify a value of -300 for this argument.
PORTABILITY
The following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for
library-specific extensions.
%A full weekday name (localized)
%a 3-character weekday name (localized)
%B full month name (localized)
%b 3-character month name (localized)
%c date and time (localized)
%d 2-digit day of month
%H 2-digit hour (24 hour clock)
%I 2-digit hour (12 hour clock)
%j 3-digit day of year
%M 2-digit minute
%m 2-digit month
%p am/pm of 12 hour clock (localized)
%S 2-digit second
%U 2-digit week of year (Sunday first day of week)
%W 2-digit week of year (Monday first day of week)
%w 1-digit weekday (Sunday first day of week)
%X time (localized)
%x date (localized)
%Y 4-digit year
%y 2-digit year
%Z time zone name
%% literal `%'
