bash: /bin/rm: Argument list too long
A glob like * expanded to more file names than the kernel allows in one command (ARG_MAX), so the command never ran.
Too many open files (EMFILE)
The process hit its file-descriptor limit — sockets, files and pipes all count.
fork: retry: Resource temporarily unavailable (process/thread limit)
The user or container hit its maximum number of processes/threads (ulimit -u, pids cgroup), so new processes can’t be created.
Go: accept tcp [::]:8080: accept4: too many open files / open x: too many open files
The process reached its file-descriptor limit — usually leaked connections, files or response bodies.
