Decreasing perNodeBufferSize and setting perNodeParallelOperations to 
server_cpu_cores * 2 may help if GC load is high.

Yes, it can be AWS related issue, either connectivity or disk I/O. There 
were reports about cluster segmentation due to network problems on AWS.
Please share full server/client logs and full thread dumps taken at the 
moment of freeze. It will certainly help in analysis.
