Hi, all We test our production kafka, and getting such error
[2015-01-15 19:03:45,057] ERROR Error in acceptor (kafka.network.Acceptor) java.io.IOException: Too many open files at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method) at sun.nio.ch.ServerSocketChannelImpl.accept( ServerSocketChannelImpl.java:241) at kafka.network.Acceptor.accept(SocketServer.scala:200) at kafka.network.Acceptor.run(SocketServer.scala:154) at java.lang.Thread.run(Thread.java:745) I noticed some other developers had similar issues, one suggestion was " Without knowing the intricacies of Kafka, i think the default open file descriptors is 1024 on unix. This can be changed by setting a higher ulimit value ( typically 8192 but sometimes even 100000 ). Before modifying the ulimit I would recommend you check the number of sockets stuck in TIME_WAIT mode. In this case, it looks like the broker has too many open sockets. This could be because you have a rogue client connecting and disconnecting repeatedly. You might have to reduce the TIME_WAIT state to 30 seconds or lower. " We increase the open file handles by doing this: insert "kafka - nofile 100000" in /etc/security/limits.conf Is that right to change the open file descriptors? In addition, it says to reduce the TIME_WAIT, where about to change this state? Or any other solution for this issue? thanks -- Alec Li
