I suspect it is locking of the file. Other candidates for this behavior
could be auto-save or backup.

Locking of remote files can be suppressed by setting
remote-file-name-inhibit-locks to a non-nil value. See also the
discussion in the Tramp manual,
(info "(tramp) Auto-save File Lock and Backup")
