This issue occurs because in carbon-transport when restarting a transport bossGroup and workerGroup is attempted to reuse after they were stopped. Reinitializing them when transport is again started will fix the issue.
Following pull request was sent to fix the issue: https://github.com/wso2/carbon-transports/pull/15 Best Regards, Samiyuru On Fri, Dec 18, 2015 at 6:26 PM, Aruna Karunarathna <ar...@wso2.com> wrote: > Hi, > > I tried to stop the jaxrs-http transport in MSS and tried to start and > ended up with the following exception.
