same here,
my 4 relays (guards) all had this log entry, with one of them the log entries are spread over a quarter of an hour (2 tor instances runnnig on this one): (this one is on Central European time zone, CET)

Same here on my bridge:
Nov 2 06:21:04 raspipfupf Tor[2556]: Possible zlib bomb; abandoning stream. Nov 2 06:21:04 raspipfupf Tor[2556]: Possible zlib bomb; abandoning stream.
Time is UTC+1, nothing before and after

We are at least 3 users running middle relays from 0.4.4.5 and after having some logs like those :
Nov 02 05:30:55.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:30:55.000 [warn] Possible zlib bomb; abandoning stream. Nov 02 05:30:56.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:31:55.000 [warn] Possible compression bomb; abandoning stream. Nov 02 05:31:56.000 [warn] Possible compression bomb; abandoning stream.I'm wondering if this is an attack or a new feature (haven't checked yet) but I'd like to know how many users are impacted.
The interesting informations are :
- Number of warnings
- What kind of relay it is (middle, exit, entry)
After your answers, I'll complete the issue I have opened on the bug tracker.
Cheers,
