AppAgent interrupted in reporting

Hello,

 

we using since 1 month the controller in version 4.5.0.25224 and the app agent in version 4.5.2.23891 with oracle java 1.8.0 update 141. MachineAgent is version 4.5.1.1385.

 

We can observe that about 10 hours after application start we receive some stacktraces and the reporting is interrupted. In this time the controller counts less calls than it is in real. After restarting the application all is fine.

Re: AppAgent interrupted in reporting

Hi @Radhika.Puthiyetath,

 

is there a workaround?

Maybe just downgrade the AppAgent to a 4.4 version?

 

with kind regards,

Raphael
