[squid-users] squid 3.5.5 - assertion failed

[Arnaud Meyer]

Hi,

I'm using Squid 3.5.5 on Debian Wheezy as a transparent proxy with https 
interception. About once per hour I'm getting the following error 
message before Squid crashes:

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


The gdb stack trace is attached below.

Any help would be much appreciated.

Arnaud
