Varnish restart because of ram filled issue

[Guillaume Quintard]

Hi,

The cache isn't the only one taking RAM, I would recommend having a look at
this article to understand what would cost you here:
https://info.varnish-software.com/blog/understanding-varnish-cache-memory-usage
Main culprit is possibly going to be Transient storage (
https://varnish-cache.org/docs/trunk/users-guide/storage-backends.html#transient-storage)
but there could be other reasons

Kind regards,
