@tomaswolf Can you help handle this issue ！！

[tomaswolf]

No, I cannot. First, I don't have the time, and second, it's not possible with just that stack trace.

Note that the channel pool used in an SftpFileSystem was changed in 2.11.0. See the relese notes and the technical docs.

[LiQingFeng7]

I tried 2.13.2 and did not have the problem again, maybe you can try the latest version
