No. Persistence is disabled in my case.

Re: Failed to wait for initial partition map exchange

[ndipiazza3565]

I'm trying to build up a list of possible causes for this issue.

I'm only really interested in the issues that occur after successful
production deployments. Meaning the environment has been up for some time
successfully, but then later on our ignite nodes will not start and stick 

But as of now, a certain bad behavior from a single node in the ignite
cluster can cause a deadlock 

* Anything that causes one of the ignite nodes to become unresponsive 
  * oom
  * high gc
  * high cpu
  * high disk usage
* Network issues?

I'm trying to get a list of the causes for this issue so I can troubleshoot
further.

How do you fix affinity key backups in cache configuration?

[ndipiazza3565]

Was just hit with this error causing my whole ignite cluster to fail to
start:

org.apache.ignite.IgniteCheckedException: Affinity key backups mismatch (fix

What does it mean by "fix affinity key backups in cache configuration" ?
