> The version I use is 2.0.0-beta-RC2. I can query data normally when cluster just have 1 segment. Once the cluster have more then 1 segments online, I cannot finish any query and being informed that "ERROR:  failed to acquire resource from resource manager, 7 of 8 segments are unavailable (pquery.c:788)".
> I have read the segment logs and the source code about resource manager. I guess this issue is because of the communication failure between segment instance and resource manager server. I can find the logs of the segment connect to resource manager successfully such as "AsyncComm framework receives message 518 from FD5" and "Resource enforcer increases memory quota to: total memory quota=65536 MB, delta memory quota = 65536 MB", but the other online segments have no these log.
