Crash

I am sometimes getting the following js stack when it crashes:

--
==== JS stack trace =========================================

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

any idea how to fix it?

I am using express-minify 0.2.0. I see there were new versions - is this issue known/fixed?

thanks

Hi, this is out of memory error. Your application hit the default Nodejs memory limit and it crashed. This may caused by several issues, for example,

1. There might be a memory leak in cssmin or uglifyjs
2. You are serving a big file so that cssmin or uglifyjs needs large amount of memory to do minification
3. You are not using disk cache so that express-minify keeps a lot of content in memory

Ways to solve:

1. Make sure you enabled disk cache
2. You can adjust NodeJs start up arguments to allow NodeJs using more memory
3. Update express-minify to use latest version of those minifiers (and hope those new versions have less memory leaks)

Hi,

Thanks for the response. I will try your potential solutions. I already tried to increase max-old-space-size but without success.

I disabled temporarily the minification to avoid crashing, as I have several other things to do currently. I will report whenever I get back to it.
