Trouble

I built my Gitea server on OpenBSD and have managed it for years.

Last month and this month, I was struggling to update it from 1.13.7 to 1.14.[0-2]. I met the fatal error about memory allocation below and failed every time.

Solution

It didn't seem to always happen on OpenBSD servers, because that in OpenBSD Ports system has been updated to 1.14. At last, I found it was because the memory size of my server was too small and seemed not to get along with Node.js and its V8 module.

I modified the updating command to add V8's max_old_space_size option of Node.js so as to limit memory consumption.

- env TAGS="bindata" make -f BSDmakefile
+ env TAGS="bindata" NODE_OPTIONS="--max_old_space_size=1024" make -f BSDmakefile
Enter fullscreen mode Exit fullscreen mode

It was successful🙂

Besides, the official documentation says:

On a machine with 2GB of memory, consider setting this to 1536 (1.5GB) to leave some memory for other uses and avoid swapping.

Description

Here are logs I got when I ran the original command and failed.

1st trial

It said "std::bad_alloc" after npx webpack but I didn't know the detail.

$ env TAGS="bindata" make -f BSDmakefile generate build
Running go generate...
generating bindata for options
generating bindata for public
generating bindata for templates
npm install --no-save

2nd trial

I ran the same command. Curiously, log has been changed without my manual change in OS, F/W or files permission.
It said clearly "FATAL ERROR: NewSpace::Rebalance Allocation failed - JavaScript heap out of memory".

$ env TAGS="bindata" make -f BSDmakefile generate build
Running go generate...

bindata for templates already up-to-date
rm -rf public/js public/css public/fonts public/img/webpack public/serviceworker.js
