SqlPredicate Operation Timeout #263
hello, all !
Our application runs correctly when we do test manually.

sorry, each of them has the same problem, but corresponding function of the exception mentioned above is as below :
We are using Hazelcast2.2. And the stack trace of exception from the server side is as below:
WARNING: [18.104.22.168]:5701 [HAZELCAST_GROUPS_1] exception during handling CONCURRENT_MAP_ITERATE_ENTRIES: [EXECUTE] Operation Timeout: -1
In addition, as the input scales sized up, We could get the same problem in manul testing.
The phenomenon below was observed several times:
After populating dataset, the size of the memory of javaw.exe was about 1,150M
Then we started the "client side" application. The size of the memory of javaw.exe on "server side" climbed to 1,500 and then outcome the exception.
The JVM is set as : " -Xms256m -Xmx1408m ".
I see, this is a issue related to no response operation timeout. It should
