Hi, We recently discovered one critical bug (kudos to Stéphane Cottin and Qian Zhang!) in CNI isolator that might cause your container to be killed when agent restarts. See more details in MESOS-9025 <https://issues.apache.org/jira/browse/MESOS-9025>.
The bug has been fixed both in 1.7.0 and 1.6.1. If you have containers that join CNI networks using CNI plugins, please skip 1.6.0 release, and wait for the 1.6.1 release. If you don't have containers that join CNI networks, it's OK to use the 1.6.0 release. Let me know if you have any question on this. Thanks, - Jie
