We've just successfully ported everything from SCO to Linux, under SCO we needed regular reboots for one lame reason or another.
Who here runs Linux in a Business or Enterprise environment? Do you guys have a policy on sheduled reboots of Linux? What reasons do you have for rebooting, or not rebooting?
Please no responses about home usage, this is a serious question for a medium size enterprise environment, and you'll get zero points cuz I'm mean!! :-p
Solved! Go to Solution.

SolutionOur development servers we reboot weekly - because sometimes we have problem with memory, IPC structures and so on
Our production servers I reboot only after applying [kernel] patches - they run without reboots many months.

Re: Regular Linux Reboots...?
we are using 3 Linux servers in product enviroment with critical 24/7 telco support aplications.
On all runs Oracle (9i or 10g), Apache2, NFS and SAMBA servers, on one runs DNS.
We have no serious reason to reboot them, memory or swap usage is ready and almost all of typical problems with Oracle or SAMBA we solve in multiuser mode without rebooting several months.
We reboot almost only in cases of upgrade, patching, hw problems

Re: Regular Linux Reboots...?
Among their roles are: Proxy,reverse http/https proxy,ftp,sftp,mail relay,smb server,nfs server,etc.
We do not reboot these servers unless there's a certain problem.
Bottom line-single reboot for at least 2-3 months.

Re: Regular Linux Reboots...?
I support customers running linux for enterprise business applications and databases. There is no rule to make reboots periodically. In general terms, if memory fragmentation or any kind of possible memory leak does not affect system performance, you don├В┬┤t need to reboot. It can be worth recycle your application instead rebooting the whole system, if this makes difference for you.
It is critical to run Linux in a certified hardware, using original manufacturer memories, CPU, IFs and disks. It will make your environment more robust. For home usage we don├В┬┤t usually see diferences in availability, in the enterprise side, a slight difference can cause your business serious damage.
My customers are used to reboot most for system updates(hw/sw).
Regards,
Celso

Re: Regular Linux Reboots...?
The only time we reboot them is if there's been some catastrophic failure of some kind, physical hardware relocation, or power failure (some people just don't like UPS for some reason!). We've not done either of these recently.
The core application boxes are running SCO binaries using ABI, and none of these have had a failure and been rebooted since we put them in (only one of them was moved).
The oldest of these is about 18 months (which was moved a month ago *pout*), the newest of which is just over a month.

Re: Regular Linux Reboots...?
I have a linux firewall runnning my cable modem and, aside from a problem with /var spilling over about 2 weeks into service, I haven't even had to look at it in over a year.
assuming you're using mostly stock modules and well tested software uptimes mesured in years are not uncommon, in fact are trivial to achive.

Re: Regular Linux Reboots...?
We are of university type with several sites, we reboot only in two cases :
- kernel patches applied
- once a year, during holliday time, cauz we just shut them down in august and turn them back on in september.
We do not see any need to reboot them in between, unless there is a special issue with one machine or another, which seldom happens.

Re: Regular Linux Reboots...?
If you had to do this on SCO, I would assume that you will have to do it on Linux too because it suggests problems with the applications you are running on it. SCO may not be the company it once once but their operating system was still a fairly useful implementation of Unix. Unix boxes don't need re-booting to keep them working.
We are a global company and the vast majority of our Windows servers are, in fact, Linux boxes. We do not re-boot them unless we are patching them or upgrading them.
I think many Linux boxes get re-booted because the admins have come from a windows background and they are used to doing that kind of thing.
