> When LRT is detected, in the case if it is active, local node creates a request to near (client) node to get the dump of a thread that created the transaction. Dump of the client node appears in server node log.
> There is new property in org.apache.ignite.mxbean.TransactionsMXBean class that shows is  thread dumps requesting allowed or disallowed:
> *TxOwnerDumpRequestsAllowed*
> By default, dump requests are turned on.
> Log messages look like following:
> {code:java}
> Dumping the near node thread that started transaction [xidVer=<xidVer>]
> Stack trace of the transaction owner thread:
> <stack trace from client node>
> {code}
> In case of client error or error while trying to read result:
> {code:java}
> Could not get thread dump from transaction owner near node:
> <stack trace>{code}
> In case of error while trying to send request:
> {code:java}
> Could not send dump request to transaction owner near node: 
> <stack trace>
> {code}
> In case if client is already out of topology:
> {code:java}
> Could not get thread dump from transaction owner because near node is now out of topology. Node ID: <node id>{code}
> In case if client does not support this feature:
> {code:java}
> Could not send dump request to transaction owner near node: node does not support this feature.
> {code}
