Alexey Goncharuk commented on IGNITE-10003:
-------------------------------------------

[~agura], [~andrey-kuznetsov], I agree that we need another failure type, but I 
do not like {{SYSTEM_CRITICAL_OPERATION_FAILED}} - semantically it is 
incorrect, checkpoint read lock timeout does not necessarily mean the operation 
failed - our recent load tests show this clearly. I agree with 
[~andrey-kuznetsov] here that {{SYSTEM_CRITICAL_OPERATION_TIMEOUT}} is a better 
fit here. For example, in future we may use the same failure type for PME 
timeouts.

> Raise SYSTEM_WORKER_BLOCKED instead of CRITICAL_ERROR when checkpoint read 
> lock timeout detected

> {{GridCacheDatabaseSharedManager#failCheckpointReadLock}} should report 
> {{SYSTEM_WORKER_BLOCKED}} to failure handler: it is closer to the truth and 
> default consequenses are not so severe as opposed to {{CRITICAL_ERROR}}.
