error: EMFILE, too many open files

skulasekar

I pulled the latest code from the repo yesterday and I get "error: EMFILE, too many open files" at startup. Upon looking further there were recommendations for using "graceful-fs" instead of "fs" module. The problems seems to have come back up again. Anyone else have the same issue.

Thanks

@skulasekar Have you tried disabling your plugins and themes to ensure it is nodebb itself giving you issues?

./nodebb reset plugins
./nodebb reset themes

Thanks for the response @mootzville , this was happening intermittently. Doesn't seem to happen now.

I know that this has been for forever since this was posted. But this can still happen.

You can check your current EMFILE limit with "uname -n". Typically this will be set to 1024.

You can raise this temporarily to something much higher like this...

uname -e 20480

That will typically fix things.

@scottalanmiller that's weird, we do use graceful-fs which should handle that automatically

It's possible in done cases this doesn't apply before an operation is executed. When did you encounter an issue?
