[Samba] smbclient sometimes fails

[Andrea Cucciarre]

Hello,

I am running a Samba server release 4.13.17 as a DC member.
On another system I periodically run the the command "smbclient -NL <samba
server IP> -g" to monitor the status of the Samba server.
Sometime (not always) the smbclient command hangs for few seconds and then
fails returning the following error message:

"smb2cli_req_compound_submit: Insufficient credits. 0 available, 1 needed
session setup failed: NT_STATUS_INTERNAL_ERROR"

Do you have any idea about what could be the cause of this odd error or any
smbclient command options that could avoid it?

Andrea
