comment why is our router crashing?
The P661HW-D1 crashes if you exceed about 900 NAT entries. Clustering downloaders (like Bittorrent) can do this.

comment Nginx+apache2 ubuntu server crashed with several hundreds of visitors
What is the actual problem? What goes wrong? Do you get error messages? Are all the services still running?

What's the router model? (P600 describes a series of about 16 routers.)

comment FreeNAS not using all installed RAM
Yeah, that rules out the first two. The third seems kind of unlikely. I think you have a mystery on your hands. Sorry I can't be of more help. Is there anything else odd in the kernel messages?

comment linux vlan routing
Do you have a router somewhere to route between these two subnets? How is 192.168.200.20 supposed to be accessed from the 192.168.100.0/24 nework? You say it doesn't work, but don't explain how/why it should work. Does 192.168.200.254 know how to reach 192.168.100.0/24 and 192.168.100.10/24 know how to reach 192.168.200.0/24?

comment FreeNAS not using all installed RAM
I only know of three reasons this happens, and none of them seem likely in your situation. 1) Onboard video controller using the memory. 2) Incorrect BIOS settings making the memory unusable. 3) Kernel memory limitations.

Why do you think it's run out of memory? What's the symptom?

comment How to investigate a memory leak with Apache and PHP?
What is the actual problem? Is performance poor? You're telling us symptoms without explaining what problem we're supposed to be helping you solve. (And what is this swapping issue you're talking about? Are you swapping so much it's impacting performance?)

comment What might cause https failure when not specifying SSL protocol?
If you can tell us the actual server, we can replicate the problem and look at the packet traces. Otherwise, we're going to have to guess.

comment IP vs domain name when setting custom name servers
I can't figure out how this question could make sense. In what case do you have to choose between using a domain name or using an IP address?

comment Increasing server storage space
Are you looking for help on adding additional physical drives? Or help on finding what's using up your space right now so you can delete it or clean it up? Or help on changing the configuration so space that's currently used for some other purpose is available for storage? Or what?

comment How do I make sure I have dedicated SSL for my site on a shared server?
It could, but it could also mean the web server needs the site name as well as the IP address to find your site.
