        This was on dnssec-schedule-fix branch code.

        I suspect it could be because of this: http://www.openssl.org/docs/crypto/threads.html. Same function calls in OpenSSL are not thread-safe.

        I think it is thread-safe if locking_function and threadid_func are set. Which we do not do. It would be great if we could reproduce the crash in order to verify the fix.

        Exactly. Since I haven't found a list of thread-safe OpenSSL functions, we should implement those functions either way.

        I've had no luck with reproducing this so far. We use SHA1 for NSEC3 and TSIG, but I don't think TSIG is used here. I only have 2 actual cores to test with though.

        Could be the same thing:

        This eventually happens when you configure two auto-DNSSEC zones with small signature lifetimes and do a lot of reloads (maybe reload is not needed, but it has not crashed without it yet, moreover, in the original backtrace, reload was done as well). There's also assertion that might fail in zones.c:792, but that's part of #155 (closed) and easily fixed.
