EFS mount randomly disconnecting

[andyland]

We've had reports of EFS mounts randomly disconnecting from instances using efs-utils. They mount and work for a while and then disappear.

Mount command:

mount -t efs -o tls,iam fs-134 /path/to/mount

Error message:

NFS: state manager: check lease failed on NFSv4 server 127.0.0.1 with error 13

Hi @andyland, thanks for reaching out. Are you able to provide any additional logs related to these random disconnects that might help us dig into this further? Alternatively, you could also open a technical support case with AWS, which will allow us to have a private channel to investigate further.
