          [JENKINS-57244] java.io.NotSerializableException: The calling thread Thread has no associated channel

          rherrick added a comment -

          This issue is absolutely killing our build server. It's appearing in many different contexts, including getting build configurations, viewing jobs, running executors, routine maintenance tasks like fingerprint cleanup, etc. There have been 4,707 occurrences in just the last three hours: jenkins.log is 32MB (attached compressed jenkins.log.gz). Jenkins is at 2.178. I keep upgrading hoping that this will be fixed but clearly it's not.

          If there's a single plugin causing the problem, I'd be happy to uninstall it but, as I noted, it's happening for lots of different operations. The biggest problem is that it's blocking the credentials store functionality, so projects that already have credentials configured have a warning "Cannot find any credentials with id <xxx>". The only options available in the credentials drop-down list are "current" and "none". If I set the credentials to "none" and save the configuration, then the only option available is "none". At some point the following message is logged:

          2019-05-20 14:36:05.974+0000 [id=10] WARNING hudson.FilePath#_getChannelForSerialization: A FilePath object is being serialized when it should not be, indicating a bug in a plugin. See https://jenkins.io/redirect/filepath-serialization for details.
          java.io.NotSerializableException: The calling thread Thread[Handling GET /credentials/store/system/domain/_/credential/<xxxx>/ from _<ip-address>_ : _<id>_ CredentialsStoreAction/CredentialsWrapper/index.jelly,5,main] has no associated channel. The current object null is interface org.jenkinsci.remoting.SerializableOnlyOverRemoting, but it is likely being serialized/deserialized without the channel

          I've got builds limping along now after dealing with weird conflicts from the authorize project plugin that may or may not be related to this issue, but I would really like a fix to this both so we can configure credentials on projects without having to edit config.xml files and to declutter the log files so that we can see any other issues that may occur.

          rherrick this was fixed weeks ago, you just need to update.

          pjelar this is fixed. What you show is a warning, not an error, about a bug in some plugin. From the log excerpt quoted it is impossible to tell which. Could probably use XmlFile.writing to help diagnose this if it is not obvious from context, but that would be a follow-up diagnostics Enhancement.

          Jesse Glick added a comment - pjelar this is fixed. What you show is a warning , not an error, about a bug in some plugin. From the log excerpt quoted it is impossible to tell which.

          As you can see, FilePath Serialization is causing the slowness in your Jenkins. We encountered this in our org and found removing FilePath fixing it. Seems like we need to get this issue reported under that plugin.

          I have lots of FilePath Serialization errors on my Jenkins master. It is version 2.222.3. Downgrading to 2.190.2 wasn't possible as the version/configuration of plugins is not backwards compatible anymore. We are suffering huge CPU load from time to time, and Jenkins becomes unresponsive. We get these errors even at boot, without any job or build running.

          This ticket is supposed to be fixed, but is definitely not fixed for us. If the problem is a plugin, it is difficult for us to investigate as we have tons, and the logs are no help to identify the source of the problem.

If the problem is a plugin, it is difficult for us to investigate as we have tons, and the logs are no help to identify the source of the problem.

          This is a warning, not an error—that was the fix.

          You would have to inspect the build.xml file on disk to determine which plugin is to blame.

          We have a similar issue with Clang Scan Build Plugin. Is there a workaround? What can be done in the plugin to fix this?
