varnish crush every 30 minutes in high pressure

[Hamidreza Hosseini]

Hi guys,
I want to upgrade my varnish but I didnt know what is difference between varnish 6.0.* and 6.5.* !
Are varnish 6.0.* LTS versions and varnish 6.5.* the latest?
which major version should I install for production?

Hi
Im using varnish , before i hadn't any problem in varnish but today after crushing my dns (I fixed it now) and in high pressure , it
restart whole machine almost every 30 minutes even Netdata that i'm using for monitoring and it shows in service status:

Sep 26 13:49:48 varnish-1 varnishd[945]: Child (1548) not responding to CLI, killed it.
Sep 26 13:49:48 varnish-1 varnishd[945]: Unexpected reply from ping: 400 CLI communication error (hdr)
