[squid-users] Problem with ssl_crtd

Wed Dec 28 17:16:26 UTC 2016

Hi everyone.

I have a strange issue with my squid 3.5.19. When I enable ssl-bump and
url_rewrite in order to make dynamic content cache, I've got, sporadically,
this error in my cache.log:

/assertion failed: Read.cc:69: "fd_table[conn->fd].halfClosedReader !=
NULL"/

When the error occur, my squid simply stops.

Here is a part of my cache.log:

If I disable ssl-bump and url_rewrite, the error does not occur. I saw here
in the list that this were a bug on squid 3.4, but I'm using squid 3.5.19.

Someone knows how to fix this?

Thanks in advance.
