Dear Cyril,

Thanks for your help.

The workaround suggested by you worked!! I changed the rsyslog setting at
client node to :

$ModLoad imfile
$DefaultNetstreamDriverCAFile /etc/ssl/rsyslog/ca.pem
$DefaultNetstreamDriver gtls
$ActionSendStreamDriverAuthMode anon
$ActionSendStreamDriverMode 1
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging on
$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

After that I stopped the rsyslog service at one of the server and checked
local logging using the logger command. However it would be really helpfull
if you could explain the reason behind this as well , also after shutting
down the syslog service at server, i can see following message at client
side, i think they are general retry message to try rebuilding the
connection with server:

'builtin:omfwd') [v8.24.0-34.el7 try http://www.rsyslog.com/e/2359 ]
