[squid-users] Problem with ssl_crtd

Thu Dec 29 00:07:43 UTC 2016

Depends on what is causing the issue.
What bug report are you writing about? Do you have a specific one that you have seen?

Also if you can disable CONNECT requests from url_rewrite it might solve an issue or two.

Subject: [squid-users] Problem with ssl_crtd

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.
