Depending on the operating system & what's running on the computer garbage collection may be an issue after a while.
2 computers here are online constantly, both Windows 7, 1 running nothing but NT/IB and a PHP program for data collection (IB has the simple "always up" mod to the config file to override the autologoff "feature") and the other running a file/web server with a database, backup program, anti-virus and a few other apps. The file server would use memory until it grinds to a halt--perhaps one of the apps has a memory leak--so I use 3rd party freeware (Minimem) to pick up where Windows' garbage collection leaves off. Even so it seems necessary to reboot both computers once in a while to "shake the bugs out".

My machine is always running (except when I give it a break in a fortnight or so). I have heard from my IT friends that machine has a better life if it runs for long time and have experienced the same.
I do close my platform though for security reasons. Till now no issues, except getting good trade each morning. Patience is required anyways!
