Hi,

 

I’m seeing some issues with extcap on linux and osx. If I run udpdump and stop it again the udp process is not terminated. If I start udpdump once again I will have two udpdump processes running on my system. I’ve tested this on v2.4.5 and v3.2.1.

 

Looking though the code I cannot find any places in extcap.c where the dumper is terminated, but for Windows it seems that the dumper process is terminated in extcap.c:1142.

 

I’ve attached a patch which seems to solve the issue, but I’m not quite sure it’s the right thing to do.

 

Best regards

Anders
