Help sir, my upstream sending me full BGP table I not ask for. Made VPS last month with Hetzner, everything fine until yesterday router crashed twice. I only ask default route sir, not 900k prefixes. My little box cannot handle this. Anyone know how fix? Thank you very much sir 🙏

Ticket open with Hetzner. Waiting. Check your filter list. Went down again. Probably their side.

Bro this happened to me before. Upstream template wrong. Since three days I fighting with Vultr same issue. Server down because RAM full from table. You check with them Important: ask their NOC

Full table is ~950k v4 + 180k v6. Filters at layer 2, scrubbing irrelevant here. 512MB RAM will choke. Ask upstream for max-prefix limit. Anycast won't help if box dies before it sees traffic.

I had the same issue with a full table once, max-prefix is the fix

2GB should survive RIB but FIB depends on kernel. Check 
ip route show | wc -l
when it happens. Hetzner NOC usually fixes template in 4-6 hours if you say "full table instead of default" in subject line.

Vultr template or you on BYOIP? Their automation sometimes ignores route object.
