[squid-users] error:transaction-end-before-headers

[Eric F.]

Hi,

I use squid 4.12 with LDAP (Active Directory).
All works great except sometimes I have the following errors in my 
access.log file :

1598438527.315      0 192.168.0.50 NONE/000 0 NONE 
error:transaction-end-before-headers - HIER_NONE/- -

How can i correct that ? Any suggestions ?

Below my squid.conf file :
