Hi all,
I have update the syslog-ng to 3.8 ( yum remove syslog-ng && yum install syslog-ng ) and change from MySQL to Mongo DB and now when i restart i have the following errors:

Error binding socket; addr='AF_INET(0.0.0.0:6514)', error='Address already in use (98)'
I'm using mutual self certification and the certificates are there in the directories "ca.d"  "cert.d". Do i have to re-create all the certificates now or can i fix this somehow.

P.S. This problem i have on the Syslog-NG Server, they all send messages to this server. So if i have to change the certificate here i will have to change on the clients too. :(

Any hints on this ?
