Version: 2.18.9

Output of final lines from strace below. The openvpn process, presumably spawned by eddie-ui,  stays up after the crash.

To restart, I kill the openvpn process manually and remove the pid file from /tmp before running Eddie. This has been happening only recently (say within the last month).

So, I ran eddie-ui with the --advanced.expert flag and got the following. Note the call to free and what seems to be an NPE:
