I'm clueless about the initial stack trace with the SIGUSR1s, but the SIGILL one you posted further below seems very odd and somewhat unrelated, but still serious.

_sparcv9_random is from OpenSSL, and while I can't find the exact version, I think it matches this piece of code:
https://github.com/openssl/openssl/blob/0e9725bcb90770d967351b977407b174bbd91869/crypto/sparccpuid.S#L347-L353

Not sure if there's an issue with the hardcoded opcode, or perhaps an incorrectly identified CPU type, but the .size line seems off. Shouldn't this read ".size _sparcv9_random,.-_sparcv9_random" instead?
