Using HAProxy to forward syslogs from rsyslog causing TCPSendBuf error

Hi all,

I am trying to use HAProxy to receive syslogs from Linux servers running rsyslog (tcp) and send them load balanced to multiple backend Logstash servers. While this works and logs are making it to Logstash, I am having issues with rsyslog showing the following error and it drops logs. This does not happen if I connect directly to Logstash. The error is happening every 50 seconds to 1 min consistently. I need a solid connection as these logs are critical. It looks like the drop is coming from HAProxy.

I really need some help with this. Also I need to add in UDP.

The error I receive in rsyslog on the Linux source is shown below

rsyslogd[512557]: omfwd: TCPSendBuf error -2027, destruct TCP Connection to

My haproxy.cfg is as follows:

    log /dev/log local0
    log-tag haproxy
    chroot /var/lib/haproxy
    user haproxy
    group haproxy

    log     global

    option  tcplog

    timeout client  50000ms
    timeout server  50000ms

    bind *:5066
    mode tcp
