Currently, our production system has more than 128 cluster modes, it is more than CONFIG_FDSET_INCR(128) . if we have client connections close to server's max client number, cluster nodes will have issue connecting each other since for each cluster node the reserved CONFIG_FDSET_INCR is not enough for reserving cluster bus connections. Is there any solution we can solve this issue? one potential solution is we can make CONFIG_FDSET_INCR configurable in config file.is there any potential risk for this? thank you!
