I'm getting the below issue

I tried adding log value="log.txt" and verbose value="true" in erlangen.sumo.cfg (in veins example) after that i triggered simulation i got same error and Omnetpp console displayed the below error.

terminate called after throwing an instance of 'omnetpp::cRuntimeError' what(): Connection to TraCI server lost. Check your server's log. Error message: 32: Broken pipe

Please guide me, I'm new to this domain.

Thank you for your message, but this is most probably not the right place to have this discussion. We're using the Veins issue tracker only to track mistakes in Veins. While there is certainly a chance that you might have found a mistake, there is also a good chance that Veins is working as it should and, rather, your problem can be solved with some guidance. May I please point you to the Veins FAQ for further guidance and a list of preferred places for having discussions. You can find the FAQ at http://veins.car2x.org/documentation/faq/

Just for completeness: I've seen that a very similar bug has been filed against SUMO (https://github.com/eclipse/sumo/issues/7090 and https://github.com/eclipse/sumo/issues/8427). The same applies here: please read the Veins FAQ for how best to get support.
