Linode stops composer update

Question

I keep having issues with updating my composer dependencies. The moment I start, I see

Loading composer repositories with package information
Updating dependencies (including require-dev)
Killed

What's causing this?

Answer 1

It's probably running out of memory, so the OS kills the proces. You might get more information from the syslog. Try adding SWAP to your Linode or using a VPS with more memory.
