Jstack shows some thrift stuff around. > kill -9 on the process makes it finally exit and then restarting works like normal. > I suspect it's because of me monkeying with iptables (rather than the network failure itself). Combined with the obvious workaround, low priority. > Not sure if it impacts later versions. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
