Reflex using 100% CPU
mikejquinn opened this issue · comments
This has happened to me a few times on OSX. I'm using the latest reflex and Go 1.9.
I'm not sure yet how to reproduce but I'll update if I get more information. I've pasted a goroutine dump below.
The config file is just watching resource files and calling make.
-r '^resources/assets/.*\.(coffee|js)$' -- make js
-r '^resources/assets/.*\.(less|css)$' -- make css

Also having this issue; -s doesn't seem to matter, and if I omit -s the CPU doesn't pin at 100% until there's a change in the file, then after running the script it pins.
Sorry for the trouble here.
I'm not sure what the problem is -- a quick browse through the goroutine dump doesn't show anything unexpected.
I updated the vendored fsnotify library in case it was a fixed bug there.
If it's not fixed, I'm going to need some hints about how to reproduce. Thanks.
I think this should be fixed now, thanks to @hartshorne.
Thanks! Will let you know if I can still replicate after updating.
