[squid-users] Squid 3.5.5 automatically reload itself in 2h rhythm

[Tom Tom]

Hi

Squid 3.5.5 on a SLES12 box with Rock and SSL-Bump enabled, reloads
itself after every 2 hours (and only if there was initial some low
traffic through it). Squid 3.3.13 on the same box doesn't reload
itself after 2 hours.

In the cache.log are no suspicious entries. Everything looks and feels
normal (the same log is shown at 06:31:xx and 08:31:xx -> every 2
hours):

Any hints for this behaviour?

Thanks a lot.

Kind regards,
