Octoprint seems to hang on startup

What is the problem?

After restart of Octoprint it is no available via the Web-UI. Browser cannot connect

What did you already try to solve it?

Login via ssh can be done without a problem.
Looking with "top", the process octoprint is consuming a lot of CPU time (140%).
In the file ~/.octoprint/logs/octoprint.log I found the line:
2021-11-15 08:48:25,426 - octoprint.filemanager.analysis - INFO - Starting analysis of local:F_Tail-1.gcode

And this was the important information. I started the last days to upload seveal gcode-Files with a "maximum mesh deviation" of 0.01mm to reduce the facet effect of large printing objects. So there were several files with about 50MB.

It seems, that the file analysis at startup time of octoprint blocks the Web-UI completely. After some minutes (the analysis was finished) Octoprint works as expected.
