SIGTERM causes main thread to exit, atexit callbacks are triggered (OPENSSL_cleanup is among them) while another threads might concurrently call openssl functions (e.g. RAND_bytes).

It can be fixed by:

  1. disable openssl atexit cleanup call
  2. join all threads

While the issue doesn't do much harm, it hides real problems and produces additional noize.
