Periodically "said redis error ... connection timed out" in varnish output

[smant]

Varnish and redis installed on separate servers.

Several times vmod-redis stopped to send any messages to redis. After restart varnish all became ok.

In varnish output I found this:

Child (12538) said redis error (command): err=1 errstr=Connection timed out
Child (12538) said redis error (command): err=1 errstr=Connection timed out
Child (12538) said redis error (command): err=1 errstr=Connection timed out
Child (12538) said redis error (command): err=1 errstr=Connection timed out
Child (12538) said redis error (command): err=1 errstr=Connection timed out

Connection to redis from varnish server is ok. Connection timeout 500ms

Maybe the vmod-redis does not reconnect it to redis after network connectivity problems?
