File Cache gets EOFError

[bill0070]

The same bug described with cachlib version 0.1.1 here: "#21", seems to appear also in version 0.2.0

I faced the same issue with 0.1.1:

[Tue Jul 06 09:57:39.680042 2021] [wsgi:error] [pid 172159] [client 127.0.0.1:38240] self._prune()

After replacing cachlib with the new version 0.2.0, this error appears again:

In both cases, the error is in picke.load(f)

Environment:

• Python version: python3.6

Thanks for letting us know. I'll close this to avoid duplicates and reopen #21 since most of the discussion regarding the issue is there.
