Description

When i use request-id plugin nanoid algorithm，file descriptor increse to the limit of worker_rlimit_nofile : 20480，then cause the error : Too many open files。

I use lsof -p command, find a lot of file descriptors like this:
openresty 955 nfsnobody 45r CHR 1,9 0t0 71005690 /dev/urandom
openresty 955 nfsnobody 46r CHR 1,9 0t0 71005690 /dev/urandom
openresty 955 nfsnobody 47r CHR 1,9 0t0 71005690 /dev/urandom
openresty 955 nfsnobody 48r CHR 1,9 0t0 71005690 /dev/urandom
openresty 955 nfsnobody 49r CHR 1,9 0t0 71005690 /dev/urandom
openresty 955 nfsnobody 50r CHR 1,9 0t0 71005690 /dev/urandom

Thanks!
