Tor crashed with segfault libcrypto.so

One of my nodes crashed today with segfault in libcryto.so. Unfortunately I cannot provide much information.

kern.log:

Nov 6 12:52:02 437673 kernel: [6711002.730880] tor[30866]: segfault at 7fc386b85000 ip 00007fc36ba94ad0 sp 00007fffa9d671d0 error 4 in libcrypto.so.1.0.0[7fc36ba29000+19f000]

During the hours before the crash I see many messages like

Nov 06 12:51:46.000 [warn] Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [58559 similar message(s) suppressed in last 60 seconds]

The number of similar suppressed messages increased over the last hours before the crash.

I updated tor to the last alpha version.
