Triage: @davidsh thinks we have a bug SslSessionCache (long existing probably)

[wfurt]

I see ~ 3K failures in the last 90 days - all on Windows failing for few different reasons.
#2352 is probably the same root cause.

[karelz]

@wfurt thinks it is related/duplicate also to failures in #34337 and #30724 ... and to #2352 mentioned above.
