I think this is a bug in the underlying library smbj: https://github.com/hierynomus/smbj/issues/864
And this error was also discussed on the Camel forum: https://camel.zulipchat.com/#narrow/channel/257298-camel/topic/SMB.20Componnent.20how.20the.20connection.20alive.3F/with/507977443 As I can see the smbj isn't properly maintained. It has 177 open issues, and no commits for 5 months. For now, I am using my custom Samba component based jcifs: https://github.com/assimbly/custom-components/tree/develop/smb Raymond On Mon, Jun 16, 2025 at 9:49 AM j_b_s34 <j_b_...@proton.me.invalid> wrote: > Hi everyone, > > I'm using a simple route to consume files from an SMB share and store them > in a database. > When the remote server becomes unreachable, the consumer keeps trying to > reconnect but seems to reuse a broken connection that wasn’t properly > closed. > The only fix is restarting the whole route. > It looks like disconnect() in SmbOperations doesn't fully close the > connection after an exception: > https://github.com/apache/camel/blob/a2fe5b8057d0c990da048a49b380b705ad2237c6/components/camel-smb/src/main/java/org/apache/camel/component/smb/SmbOperations.java#L116-L134 > > https://github.com/apache/camel/blob/a2fe5b8057d0c990da048a49b380b705ad2237c6/components/camel-smb/src/main/java/org/apache/camel/component/smb/SmbOperations.java#L116-L134 > > Kind regards, > jubar. > > StackTrace: > com.hierynomus.smbj.common.SMBRuntimeException: > com.hierynomus.protocol.transport.TransportException: > java.net.SocketException: Broken pipe > at > com.hierynomus.smbj.connection.SMBSessionBuilder.establish(SMBSessionBuilder.java:124) > at > com.hierynomus.smbj.connection.Connection.authenticate(Connection.java:206) > at > org.apache.camel.component.smb.SmbOperations.connectIfNecessary(SmbOperations.java:91) > at > org.apache.camel.component.smb.SmbConsumer.prePollCheck(SmbConsumer.java:207) > at > org.apache.camel.component.file.GenericFileConsumer.poll(GenericFileConsumer.java:129) > at > org.apache.camel.support.ScheduledPollConsumer.doRun(ScheduledPollConsumer.java:208) > at > org.apache.camel.support.ScheduledPollConsumer.run(ScheduledPollConsumer.java:119) > at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown > Source) > at java.base/java.util.concurrent.FutureTask.runAndReset(Unknown Source) > at > java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown > Source) > at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown > Source) > at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown > Source) > at io.opentelemetry.context.Context.lambda$wrap$1(Context.java:241) > at java.base/java.lang.Thread.run(Unknown Source) > Caused by: com.hierynomus.protocol.transport.TransportException: > java.net.SocketException: Broken pipe > at > com.hierynomus.smbj.transport.tcp.direct.DirectTcpTransport.write(DirectTcpTransport.java:86) > at com.hierynomus.smbj.connection.Connection.send(Connection.java:242) > at > com.hierynomus.smbj.connection.Connection.sendAndReceive(Connection.java:247) > at > com.hierynomus.smbj.connection.SMBSessionBuilder.initiateSessionSetup(SMBSessionBuilder.java:217) > at > com.hierynomus.smbj.connection.SMBSessionBuilder.setupSession(SMBSessionBuilder.java:136) > at > com.hierynomus.smbj.connection.SMBSessionBuilder.establish(SMBSessionBuilder.java:119) > ... 13 more > Caused by: java.net.SocketException: Broken pipe > at java.base/sun.nio.ch.SocketDispatcher.write0(Native Method) > at java.base/sun.nio.ch.SocketDispatcher.write(Unknown Source) > at java.base/sun.nio.ch.NioSocketImpl.tryWrite(Unknown Source) > at java.base/sun.nio.ch.NioSocketImpl.implWrite(Unknown Source) > at java.base/sun.nio.ch.NioSocketImpl.write(Unknown Source) > at java.base/sun.nio.ch.NioSocketImpl$2.write(Unknown Source) > at java.base/java.net.Socket$SocketOutputStream.write(Unknown Source) > at java.base/java.io.BufferedOutputStream.flushBuffer(Unknown Source) > at java.base/java.io.BufferedOutputStream.implWrite(Unknown Source) > at java.base/java.io.BufferedOutputStream.write(Unknown Source) > at > com.hierynomus.smbj.transport.tcp.direct.DirectTcpTransport.writeDirectTcpPacketHeader(DirectTcpTransport.java:163) > at > com.hierynomus.smbj.transport.tcp.direct.DirectTcpTransport.write(DirectTcpTransport.java:81) > ... 18 more > > Sent with [Proton Mail](https://proton.me/mail/home) secure email.
