Not able to run multiple varnish instances on single maschine - Pushing vcls failed:#012CLI communication error (hdr)

[Arne Mohr]

Hi folks,

i have a problem when i try to run multiple varnish instances on a single
maschine. I have 3 varnishes running on Port 80,81,82 the starting
parameters are:

/usr/sbin/varnishd -P /var/run/varnish-www.portal-a.de.pid -a
10.10.145.41:80 -T localhost:6080 -f /etc/varnish/www.portal-a.de.vcl -S
/etc/varnish/secret -u varnish -g varnish -t 28800 -w 10,1000 -n
www.portal-a.de -i frontend -p thread_pools 4 -p thread_pool_max 1024 -p
thread_pool_min 250 -p listen_depth 2048 -p thread_pool_add_delay 2 -s
malloc,1G

/usr/sbin/varnishd -P /var/run/varnish-www.portal-b.de.pid -a
10.10.145.41:81 -T localhost:6081 -f /etc/varnish/www.portal-b.de.vcl -S
/etc/varnish/secret -u varnish -g varnish -t 28800 -w 10,1000 -n
www.portal-b.de -i frontend -p thread_pools 4 -p thread_pool_max 1024 -p
thread_pool_min 250 -p listen_depth 2048 -p thread_pool_add_delay 2 -s
malloc,1G

/usr/sbin/varnishd -P /var/run/varnish-www.portal-c.de.pid -a
10.10.145.41:82 -T localhost:6082 -f /etc/varnish/www.portal-c.de.vcl -S
/etc/varnish/secret -u varnish -g varnish -t 28800 -w 10,1000 -n
www.portal-c.de -i frontend -p thread_pools 4 -p thread_pool_max 1024 -p
thread_pool_min 250 -p listen_depth 2048 -p thread_pool_add_delay 2 -s
malloc,1G

The first varnish ist starting up correctly and is also able to process the
incoming requests. Also it's child process is forked in a correct way.
The problem I have occurs when  I try to  start the second varnish.

I found following log entries in my syslog

May 14 14:12:51 webcache01 www.portal-b.de[10021]: Platform:

May 14 14:12:51 webcache01 www.portal-b.de[10021]: Child (-1) said   errno

At the moment I'm stuck with my problem and I'm not able to find whether a
solution nor a starting point.
Maybe anyone had a similiar problem and has some tips for me?

With best regards!
