Someone has any idea what's happening?
IIRC, this is an SSL parsing bug in older Squids. Sorry, I do not have a
reference. If you are using SslBump, you should upgrade to the latest
v3.5 (at least).

Alex.
I'm already using squid 3.5.7.

Which is already 5 months outdated. TLS and SSL related things are changing on an almost weekly basis, even in the stable/production version.

I'll try to upgrade to 3.5.12.
I was look for this, but didn't find anything,  do you have some link
about this?

Yes:

 "crash or high CPU usage".
