I guess there's no need for that. Your varnishlog setup is stretched
too thin to cope with your load.

I was completely oblivious to the problems slink spotted right away...

Because all the clients which are reading shm all are getting same thing..means no ReqAcct. But yes I am agree that impact with "varnishlog -g session" is more.

You could try avoiding grouping, use varnishncsa with a custom format,
overall store and process less data in memory.

There are few practical uses of -g session for live traffic. This
works better on offline logs for example when examining traffic

If only ReqAcct is important, and the rest of the information you need
is available on the request side, you should definitely stop using the
-g option, and use the -c option to further limit internal processing.

If you need information from the backend transactions too, try to
figure how you could make this information available on the client
