Fatal error occurred during execution of 'Server Core'

bug?
1

I am getting the below error in my logs, I have already upgraded the hangfire to 1.3.1. Does anyone know about how this error should be dealt with?

“Fatal error occurred during execution of ‘Server Core’ component. It will be stopped. See the exception for details.”

Thanks!

I’ve recently release Hangfire 1.3.2, and instead of failing instantly on any exception during the start, it will retry it several times. However, only logging an inner exception will help to identify a problem. What logging library are you using?

Our app is using NLog library form logging.

We are using the following layout for our applications to store exceptions also, look at the ${exception} tag:

<target name="logfile" xsi:type="File" layout="[${longdate}] ${level:uppercase=true:padding=5:fixedLength=true} - ${logger:padding=30:fixedLength=true} - ${message}${onexception:${newline}${newline}${exception:format=Message,Type,Method,StackTrace:innerFormat=Message,Type,Method,StackTrace:maxInnerExceptionLevel=10}${newline}}" fileName="${basedir}/../gamezone.log" archiveEvery="Day" concurrentWrites="false" />
