It depends just how outdated your libevent is.

And what platform you're running it on, which dictates what
system call it prefers to use: select, poll, kqueue, etc.

Tor tries to warn you if it sees a combination of a platform and
libevent version that it knows is especially bad:
see check_libevent_version() in src/or/config.c

But if you're encountering problems and you're using an old libevent,
upgrading your libevent is often a good place to start.
