Error when visiting cubes by endpoint

HI:
     I always hang up when I'm using kylin, and then kylin.log throws this mistake
"2017-11-06 09:39:51932 ERROR [pool-6-thread-4469] v2.CubeHBaseEndpointRPC:404 for GTScanRequest 3c48f6fb> Error: <sub-thread when visiting cubes by endpoint "and" Error in coprocessor “, kylin.out throws the mistake"
Exception in thread "Thread-12" java.lang.RuntimeException: java.lang.RuntimeException: java.lang.OutOfMemoryError: unable to create new native thread”，so, what other good suggestions do you have?

Thanks!

What kind of queries you were using. Please try some aggregated query, not
detail query. For example select XXX, count(*) from table group by XXX.
