Update to 0.27.2 or wait for 0.28.0. I experienced many crashes as well with 0.27.1 due to crashes in the frameworks bringing down the whole cluster (swarm specially). Also problems in the resource precision that also crashed the servers and crashes when nodes disconnected.
I really found 0.27 very unstable. Many of this problems were solved for 0.27.2 and my latest environment has proven way more stable. It is still not fully stable as the cluster crashed yesterday due to a crash in marathon, but way better overall and quick to recover. Luck!

Any logs (master, agent, application) that can shed light would be useful to diagnose.

However, I have faced many crashes and I couldn't find what it is the matter. We have 14 machines with 8Gb of ram and 4 cpu each. Usually, we run about 40 instance of our crawler, which they start stopping of nowhere (but the containers keep running). The day before yesterday we decided try to test our entire infrastrcuture and we scaled our crawler up to 110 instances. Unfortunately, today we've faced a big crash that affected mainly our crawler and our databases. So, I am wondering if anyone else have the same problem, such as apps which crashes of nowhere or something else which could be related to some unstability on Mesos. -- Alfredo Miranda
