Major Hi,
we observed Jenkins agents disconnecting during pipeline execution.
Unfortunately it happens rarely and it's hard to pinpoint exact root cause.
Quite often it occurs during finishing of TestComplete tests.
Error I got is
[2025-01-14T12:29:01.547Z] [TestComplete] [ERROR] An exception occurred:
[2025-01-14T12:29:01.547Z] java.nio.channels.ClosedChannelException.
Followed by another one during post actions:
Error when executing always post condition:
Also: org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: 54bbc34a-e9b0-407c-9866-a0b807f89a82
org.jenkinsci.plugins.workflow.support.steps.AgentOfflineException: Unable to create live FilePath for TSLDESOT118
Same issue appeared few times for different machines.
I'm not sure if it's related but we also saw such INFO logs on Jenkins instance during this time:
2025-01-14 12:29:00.512+0000 [id=424462] INFO j.s.DefaultJnlpSlaveReceiver#channelClosed: IOHub#1: Worker[channel:java.nio.channels.SocketChannel[connected local=/10.100.29.20:56429 remote=TLSDVSOT118.company.com/10.128.80.30:62895]] / Computer.threadPoolForRemoting 53461 for TLSDVSOT118 terminated: java.nio.channels.ClosedChannelException
Those logs appeared almost for all machines, but we only saw similar issue only on 3 of them.
In attachment I'm adding full log of execution
