Vyacheslav Tutrinov commented on HDDS-9316:
-------------------------------------------

An implementation expectation is:

{code:java}
try {
    handleRatisMessage();
} catch (Throwable ex) {
    handleException(ex)
}
{code}

> OM: exception handler on top level

> Issues like HDDS-9196 can crash an ozone cluster. An existing code base and 
> new code peices can have a lot of problems theoretically, and they shouldn't 
> kill the OM instances. Hence, all of the ratis messages should be handled in 
> a top level {{try..catch}} block to avoid the server crashing
