Environment (please complete the following information):

• OS: OpenBSD 7.5以上
• Matterbridge version: 1.26.0
• If self compiled: c4157a4

It compiled fine on OpenBSD 7.4 and earlier.

That's not a bug in matterbridge. Instead, just don't use all the RAM at the same time.

One way to deal with it is to compile sequentially, and not in parallel. For example, on a machine with particularly low memory I use:
go build -tags nomsteams,nozulip -p 1 -v

This server has 16 GiB of memory, and it's normally not over 2 GiB.
So it can't be a memory issue.

This is in action
thank you

This server has 16 GiB of memory, and it's normally not over 2 GiB.

The compilation process seems to take (rough estimate) about 1-3 GB per thread. So if you system has 8 or more cores, then GOMAXPROCS defaults to that same "8 or more", resulting in OOM.

Matterbridge really should have a better mechanism of limiting build parallelism. Can you write a PR to add appropriate warnings in the readme or log messages?
