Before I file a bug…. any ideas?

Got valid certs, working fine for everything I need them from, but this seems to popup randomly in my logs.

[Feb 9 12:43:07] ERROR[14968]: iostream.c:507 ast_iostream_close:
SSL_shutdown() failed: error:00000005:lib(0):func(0):DH lib, Underlying BIO
error: Bad file descriptor

Something I’m doing?
