[syslog-ng] Reason why syslog-ng service dies frequently

[Nguyen Trung Hieu]

Dear team
I have instaled syslog-ng version 3.5.4.1 on Centos 6.5 32 bit for 4
months, recently it dies very frequently, after I restart service it only
work for some hours then die again. I have checked but still don't know
why. Can anyone help me on this. Thank you.
Below is log from my Centos box, I also attached my syslog-ng config file.
