Moulinette lock disappeared after huge backup creation

Hi, when doing backup within Yunohost and Seafile (approx. 200GB) Iv got errors according to below. I don't get this errors if I exclude Sefile to backup (5GB). First reported here - https://github.com/YunoHost-Apps/seafile_ynh/issues/61

Traceback (most recent call last):
  File "/usr/bin/yunohost", line 218, in <module>
    timeout=opts.timeout,

Hi o/ I'm no expert, just passing by, but from your log, it seems that a general "timeout" is reached... I wonder if there is such a setting in core... If so, I guess you could change its value before starting your backup.

Other theory: another process grabs the lockfile, do you run any automatic script during your backup ?

(If you can provide more context: what is your hardware setup ? does the backup operation actually last for a while before getting this error ? And maybe a core maintaner could use your full log)

(Not sure how that happens, but I guess an easy fix is to add an if os.exists(self._lockfile) before that unlink ...)
