RE: Failed to read data from remote connection

When check connections,Many nio socker will be create(one socker per node) ,Then direct memory will grow up with the node count? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

RE: Failed to read data from remote connection

Not really. The amount of direct memory needed doesn’t grow with the node count nor the amount of data you store. Stan From: wangsan Sent: 12 января 2019 г. 9:30 To: user@ignite.apache.org Subject: RE: Failed to read data from remote connection Yeath, set a larger MaxDirectMemorySize . But, I

RE: Failed to read data from remote connection

Yeath, set a larger MaxDirectMemorySize . But, I am afraid of when nodes size be more larger.The directmemory will be larger with node sizes. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

RE: Failed to read data from remote connection

“OOME: Direct buffer memory” means that MaxDirectMemorySize is too small. Set a larger MaxDirectMemorySize value. Stan From: wangsan Sent: 18 декабря 2018 г. 5:08 To: user@ignite.apache.org Subject: Re: Failed to read data from remote connection Now the cluster have 100+ nodes, when 'Start

Re: Failed to read data from remote connection

Now the cluster have 100+ nodes, when 'Start check connection process' happens, Some node will throw oom with Direct buffer memory (java nio). When check connections,Many nio socker will be create ,Then oom happens? How to fix the oom except larger xmx? Thanks. -- Sent from:

Re: Failed to read data from remote connection

Do you shut down C++ node properly prior killing the process? Yeath, c++ node was killed by kill -9 .not sighup. It is a wrong ops,And I will use kill ops. Does this exceptions impacts cluster's functionality anyhow? I am not sure about the exceptions. My cluster will crash with oom

As I restart cpp client many times concurrently ，may be zkcluster(ignite) has some node path has been closed. >From cpp client logs , I can see zkdiscovery watch 44 first,but the node has been closed

Re: Failed to read data from remote connection

I have a cluster with zookeeper discovery, Eg java server node s1,java client node jc1 and cpp client node cpp1 Sometimes when cpp1 restart ,s1 and jc1 will throw this exception many times Failed to process selector key [ses=GridSelectorNioSessionImpl And cpp1 with have many messages

Can you explain your case in more detail? I'm not quite understand what the problem is. Best Regards, Igor On Tue, Nov 27, 2018 at 1:27 PM wangsan wrote: > When client （c++ node） restart mulit times, > The server and other client will throw this excption > > ERROR
