Hi!
We have exceeded the limit of open files on server. Kong write to log file next:
2019/11/01 06:01:13 [crit] 22660#0: accept4() failed (23: Too many open files in system)
2019/11/01 06:01:13 [crit] 22658#0: accept4() failed (23: Too many open files in system)
2019/11/01 06:01:13 [crit] 22659#0: accept4() failed (23: Too many open files in system)

But in log we have errors with ssl handshake:
2019/11/01 09:54:22 [error] 22660#0: *13950752 lua entry thread aborted: runtime error:
/usr/local/openresty/lualib/resty/core/misc.lua:103: API disabled in the current context
stack traceback:

ssl_certificate_by_lua:2: in function <ssl_certificate_by_lua:1>, context: ssl_certificate_by_lua*, client: 15.135.16.4, server: 0.0.0.0:443
How do limits of open file lead to handshake problems?
