If it is normally there, it means that you have exhausted your physical RAM that is available and are now hitting almost 100% of the disk swap space used when that happens. I am not surprised that it went offline. In effect - you have outgrown (if this is constant) the hosting your are on or you have some seriously heavy processes running in the background (either run-away or normal). If runaway processes you need to get them fixed - if normal then it's time for a server (hosting plan or VPS memory) upgrade if this is near constant.

In simple terms, under linux swap serves essentially the same function as virtual memory in windows with a slightly different implementation (a partition rather than a file). It is used for lower priority pages (blocks of memory) which get swapped so a higher priority can use the actual memory which is faster than your disks which swap uses.

Is this a shared hosting environment that you do not have shell access to? If you have shell access, what is free -h showing.
Sounds like it may be a problem in their config. New kernels should not be using "all the swap" unless their is a problem.
This is from one of my servers
Code:
tracy@pegasus:~$ free -h
total used free shared buffers cached
Mem: 23G 3.7G 19G 0B 269M 2.0G
-/+ buffers/cache: 1.5G 22G
Swap: 14G 0B 14GThis is from a server running ProxMox (which is a virtualization setup to allow VPS's to be served from it)
Code:
tracy@smokey:~$ free -h
total used free shared buffers cached
Mem: 23G 2.9G 20G 0B 153M 265M
-/+ buffers/cache: 2.5G 21G
Swap: 22G 0B 22GAnd this is from one of the VPS's set up on the above server
Code:
tracy@support:~$ free -h
total used free shared buffers cached
Mem: 1.5G 559M 947M 0B 160M 253M
-/+ buffers/cache: 145M 1.3G
Swap: 3.0G 0B 3.0GTPerry

@Robby, doing some research reveals that the SWAP issue appears to be how they have their server configured and they "say" it has no impact on your services (but I think you are seeing different). You are probably either hitting CPU limits or memory (I haven't found anywhere on their site that lists how much each semi-dedicated has assigned to it - only CPU info and bandwidth/disk allocations).
What have they suggested (I've heard good things about them so you can probably rely on what they tell you). They are using Cloud Linux (from what I have read)? I haven't (yet) had any exposure to that virtualization setup (currently getting a dedicated configured with CloudLinux installed on it so soon will have).
If you want some info on it (from them) hit this page up.

Fancy marketing name for shared hosting.
Are you familiar with administering Linux? If so, I'd suggest going with a VPS (or if you don't mind around $80 a month you can get a dual L5639 with 2 1TB SATA drives in RAID 1 software config at a certain provider I'm very fond of - I have 3 servers with 'em now and have had excellent support when I needed it). Doubt you would outgrow that very soon.

IF UK based, I've heard good things about them but have no first hand experience. All my servers are US based (and the VPS's I've used before them).

Nimbus to Belgium for hosting should be fine. @Chris Deeming is with Nimbus, so check http://xenmediagallery.com/ or http://www.valvetime.net/ and see how they load.

Seems pretty fast to me
