Hi (yes again): We have a simple architecture: 2 SOLR Cloud servers (on servers #1 and #2), and 3 zookeeper instances (on servers #1, #2, and #3). Things appear to work fine, and I have confirmed that our basic configuration is correct. But we are seeing TONS of the following warnings in all of our zookeeper server logs:
2019-01-04 14:48:04,266 [myid:1] - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@192] - Accepted socket connection from /XXX.YY.ZZZ.46:51516 2019-01-04 14:48:04,266 [myid:1] - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@368] - caught end of stream exception EndOfStreamException: Unable to read additional data from client sessionid 0x0, likely client has closed socket at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:239) at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:203) at java.lang.Thread.run(Thread.java:748) 2019-01-04 14:48:04,266 [myid:1] - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1044] - Closed socket connection for client /XXX.YY.ZZZ.46:51516 (no session established for client) These messages seem to correspond to similar message we are seeing in the application client-side logs. (I don’t see any messages that would indicate Too many connections.) Reading the log content, it seems to be saying that a connection is accepted, but then there is an "end of stream" exception. But our users are not experiencing any problems--they are searching SOLR like crazy. Any suggestions? Thanks! Joe -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
