SSH - git-upload-pack warnings

Mahesh Vecham

Hi Team,

Recently we have upgraded Bitbucket 7.2.1 to 7.21.14 We can see in the logs that they are overflowed with some Java error:

2024-01-11 11:00:46,359 WARN  [ssh-scm-request-handler] 8c4206f147967552 @1THBEWVx660x885x2 1353evp 10.24.141.238 SSH - git-upload-pack '/<repo url>.git' c.z.n.windows.ProcessCompletions Aborting processing loop after unexpected exception (2 processes running)

java.lang.RuntimeException: CreateIoCompletionPort() failed, error code: 6

                                   at com.zaxxer.nuprocess.windows.WindowsProcess.run(WindowsProcess.java:279)

 

The logs are typically 1GB big, we are using Teamcity to build. Any help on this why this is happening?

Hi Mahesh,

The stack trace you shared is typically an indication of another problem, not the cause. Unfortunately, the cause may vary and we would need more information.

Debug logging would tell us more about the issue. If log files are already 1GB in size, then it is possible that you already have debug logging enabled; in which case you can try filtering the logs by the request ID (1THBEWVx660x885x2) to see what else got recorded.

In case debug logging is not enabled, then you will have to turn it on, wait for the problem to re-occur and check the logs. Something tells me the problem is somewhat consistent in your environment, so it shouldn't take longer until it surfaces again.
