Discourse update error with Terser

Error: assets/chunk.cbb4d6362a2090db10ec.d41d8cd9.js from Terser plugin failed to handle:
  failed printing to stdout:
  Resource temporarily unavailable (os error 11)

Could be a shortage of virtual memory: try adding RAM or adding swap. (Fork failing with EAGAIN can be memory shortage)

Have a look at

free -h
vmstat 5 5

There are two kernel tunables which can improve memory efficiency

cat /proc/sys/vm/overcommit_memory
cat /sys/kernel/mm/transparent_hugepage/enabled
