iperf -c <IP> causes SIGSEGV on VMware #412

Open syuu1228 opened 9 years ago

syuu1228 commented 9 years ago

On VMware I got SIGSEGV after benchmark finished. It looks like iperf trying to access invalid address, but only happen on VMware, not on KVM.

I think this issue was discussed here already. The problem is either alarm of thread left by iperf on exit.
