Hi, I am using Kafka 0.8.2.1. We have 1 zookeeper, 3 kafka brokers. We have 9 topics, out of which 1 topic has 18 partitions, while another has 12 partitions. All other topics have 1 partition each.
We see that idle kafka brokers (not carrying any message) are using more than 50% of CPU. See top output below. Is this a known issue? Thanks top - 04:42:30 up 2:07, 1 user, load average: 1.50, 1.31, 0.92 Tasks: 177 total, 1 running, 176 sleeping, 0 stopped, 0 zombie Cpu(s): 13.5%us, 4.5%sy, 0.0%ni, 81.3%id, 0.2%wa, 0.0%hi, 0.1%si, 0.4%st Mem: 65974296k total, 22310524k used, 43663772k free, 112688k buffers Swap: 0k total, 0k used, 0k free, 13382460k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 9295 wae 20 0 5212m 894m 12m S 62 1.4 22:50.99 java 9323 wae 20 0 5502m 894m 12m S 56 1.4 24:28.69 java 9353 wae 20 0 5072m 896m 12m S 54 1.4 17:04.31 java
