Apparent Infinite loop when executing 'steam'

[Samsam]

I'm using a Ubuntu Server OS on the Oracle Virtual Machine.

After going through these steps: http://www.srcds.com/db/engine.php?id=1098643920

It's become apparent that the virtual machine enters some kind of loop it can't break out of when I do './steam' to update it OR when I run './srcds_run'.

When I use sudo it works fine, though the CSS server I installed asks me not to run it as root (and I definitely do not want to) but I shouldn't need to use the sudo command so there's definitely something amiss.

Terminal snapshot, sudo ./steam (working fine):

Code:

sam@ubuntuserver:/home/steam/srcds_l$ sudo ./steam
[sudo] password for sam:
Checking bootstrapper version ...

Use: steam -command <command> [parameters] [flags]

Commands:

update: Install or update HLDS

   parameters:
      -game <game>            -   Game name (use '-command list' to see available games)
      -dir <installdir>       -   HLDS Install dir
      (if dir not specified, will use value from last run of tool)

   flags:
      -verify_all             -   Verify all HLDS files are up to date
      -retry                  -   Automatically retry every 30 seconds if the Steam Network is busy
      -remember_password      -   Remember password (if a username is supplied)

   For example: steam -command update -game cstrike -dir /hlds

version: View installed versions

list: View available games

Optional parameters for all commands:

      -username <username>    -   Steam account username (only needed to access limited content)
      -password <password>    -   Steam account password (only needed to access limited content)

CAsyncIOManager: 0 threads terminating.  0 reads, 0 writes, 0 deferrals.
CAsyncIOManager: 8 single object sleeps, 0 multi object sleeps
CAsyncIOManager: 0 single object alertable sleeps, 0 multi object alertable sleeps

Not using sudo

Code:

sam@ubuntuserver:/home/steam/srcds_l$ ./steam
Checking bootstrapper version ...
removing stale semaphore last operated on by process 1417 with name 0eBlobRegistryMutex_A7CD3883333D1020A7C035F1967908A1
removing stale semaphore last operated on by process 1417 with name 0eBlobRegistrySignal_A7CD3883333D1020A7C035F1967908A1

The terminal will stay like this until I cancel it.
My network monitors show nothing so it's not waiting for a download to complete.
The same also happens when running './srcds_run', it works when using sudo but hangs when I run it normally (hanging on the same line).

The process also takes all the CPU it can get, as shown by top:

Code:

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
1432 sam       20   0  5272 2188 1396 R 97.7  0.1  26:54.59 steam

Anyone got a clue?
