 @plainbroke 
 Hi,
 my mm.sh also restarts the mirror. But my intention with was doing only a refresh to save a lot of time. My restarts script sleeps 15s before it is executed. So i created a seperate refresh script.

 Ok mine doesn’t wait. I usually do a list of changes I have researched.
 So the complete restart of MM is ok for me.
 Right now trying to figure out a couple of modules that are not loading…
- 
 @plainbroke interesting, my file and your have just two changes - you have the cwd: setting
- you have followSymlinks (which we don’t have any of)
 I added cwd to mine and now MM restarts… weird 
- 
 @sdetweil 
 Glad it works for you.
 I have no Idea where it came from. I would guess from someone on this forum.
- 
 @plainbroke well, mine looks nearly identical… just missing the cwd… I opened an issue about this 2 years ago, never got a response… 
 and adding cwd (current working directory)I don’t know how that matters… but whatever… it works now…
