At the moment, we are getting an average of 20 to 30 days uptime on
our L's, running 64 bit 6.2 with a generally heavy multi-user load,
and 60 to 100 days or so of uptime on the Indy's and S's which
are dedicated to particular functions (such as DNS, irc, and sendmail).
The challenge S's with medium to heavy multi-user loads tend to stay up
around 40 days. Sometimes the kernels get confused and have to
be rebooted to regain performance or resources, though this has happened
less often in recent times (except the paging code is still extremely
broken in terms of its performance under load). The L's do this more
then single processor boxes. The uptime is much improved over 6 months
ago where the L's couldn't stay up for more then a couple of days without
crashing.
The FreeBSD machines tend to stay up for months (100+ days with a medium
to heavy user load, or a heavy dedicated load) and basically not die
unless a disk goes south or, in a recent case, one machine tickled a
SCSI driver bug. We generally reboot them only to load new kernels or
I'd have even more impressive numbers to report.
