SolutionBasically I reboot only for patch installations (if required) and/or for hardware upgrades (obviously).
This question was recently asked with quite a few replies too, in this thread:

Re: how often do you reboot your servers?
I reboot my servers once a month. I have one weekend a month that I get the machines without any users. That allows me to reboot, load patches, or whatever else is required. It seems to work pretty well.
You will find a lot of different opinions on this. I know of some machines that have been left up for years without a reboot. I just depends on what is running on the machine and how well the code was written.

Re: how often do you reboot your servers?
We do have a production server, that is used 24x7. It's
really difficult to get a window that would allow me to reboot the K570. So, we do not reboot the server as per say; only when there are patches that must be applied.
At the previous place I worked, once a month we were
rebooting the server. IT was part of the routine.
Honestly, I don't see any difference. I think it's much a
matter of taste.

Re: how often do you reboot your servers?
I'm a fan of not creating extra work. If your servers are running fine, don't mess with them. Leave them up.

Re: how often do you reboot your servers?
I reboot our ingite server only when HP Education sends me a new disk, which is about once every quarter.
My test box under my desk gets reboot about once a quarter for patches or user induced crashes :).
The student machines get booted frequently and every which way imaginable including having the power cored pulled. No ill effects yet (although the OS is reinstalled weekly for new classes).

Reboot the server only and only when needed.

Re: how often do you reboot your servers?
But for any buggy application (like memory leak problems) there should be a patch available one day. So in long term you should be able to elimnate the need of regular reboots.
In my opinion you don't win anithing by rebooting a stable server. But you have the risc that something goes wrong during this procedure.

Re: how often do you reboot your servers?
He also recommended bringing the system to a halt every six months. This is to test to see
if the disks are healthy

Re: how often do you reboot your servers?
If your filesystems were unmounted cleanly, then fsck is typically not run when the system boots. If it does, it is usually just a replay of the intent log (for vxfs filesystems). If you really want to run fsck, which is not a bad idea, then boot to runlevel s and run it manually. For vxfs filesystems,
fsck -ofull,nolog /dev/vgXX/rwhatever
