I had an issue giving me lots of errors in my apache log about MqDriver.php so i fresh installed 8.2.1 and put all personal files back, all accounts were still in the database (luckily) and now im getting this error filling my logs instead:

```
The process tried to write to a nonexistent pipe.
The batch file cannot be found.

```

Just like what can be found here (no solution provided):  
[https://pydio.com/forum/f/topic/unkonwn-parsing-error/](https://pydio.com/forum/f/topic/unkonwn-parsing-error/)

Everything seams to work fine tho, my users can find allt their files, upload and download but i believe it might be an issue with Opcache?

Im just gonna keep trashing my logs since those are the only two massages i get there. in case i find something new ill keep it tho.

My setup:  
Windows Apache, MySQL 5.7.19, PHP 7.2.8
