--- Comment #8 from Daniel Ruggeri <> ---
For those seeing the issue: Are you using an engine (SSLCryptoDevice)? I know
some register their own callbacks for locks - not sure if that's coming into

I see similar behavior as well on Solaris 10 w/ worker in openssl-0.9.8u, but
far fewer zombie processes. This is on a particularly busy production install
rather than under a load test scenario. Just like the original bug, I see a few
threads interacting with a proxied resource with most threads sitting in
CRYPTO_add_lock. There is at least one zombie thread in 5 of the 6 running
child processes. The child process without any zombies are still sitting in

I can attach pstack output as well, but the short version is:
*Very few threads doing work
*Many threads waiting in CRYPTO_add_lock
*Did not seem to happen in 2.2.13 w/ openssl-0.9.8l with an otherwise identical

Happy to provide more info if needed
