LYR-RT0015

the system refused the runtime what it needs

panic · spec 13-abi

The operating system refused the runtime something it cannot go on without: a poller for I/O and timers, its wakeup, a pipe for signals or child processes, random bytes, a thread's attachment to the collector. No program text causes it; the machine's limits or state do (too many open descriptors, for example).

Example

$ ulimit -n 3
$ ./out/debug/app
panic [LYR-RT0015]: the system refused a poller: Too many open files
