Syslog messages get truncated at 1kb (syslog server config is ok)

[Damiano Giorgi]

Hi all,
I'm looking for help on this little piece of config:

global
    stats socket /tmp/haproxy.sock mode 0600 level admin
    user haproxy
    group haproxy
    daemon
    log syslog.7pixel.local len 8192 local0
    pidfile /var/run/haproxy.pid
    stats socket 192.168.0.191:8080 level admin

defaults
    log     global
    mode    http
    option  dontlognull
    retries 3
    option redispatch
    maxconn 2000
    timeout connect      5000
    timeout client      50000
    timeout server      50000

Even if I set 8192 as length the message gets truncated after 1024 chars, we 
use syslog-ng and configured it to accept a ridiculously huge length 
(log_msg_size(262144) defined in /etc/syslog-ng.conf), I also tried using the 
logger utility to check if the message gets delivered correctly and it does.
I'm currently running haproxy-1.5.12 on a debian 7 system, compiled with: make 
TARGET=linux2628 USE_PCRE=1 CPU=native USE_OPENSSL=1 USE_ZLIB=1  PREFIX=/usr

Am I missing something ?

Thank you for your help

Damiano
