squid 3.5.5 - assertion failed

Arnaud Meyer <meyer@xxxxxxxxxxxx> · Tue, 21 Jul 2015 11:58:58 +0200



    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
