HTTP 500 error twice in one month?
That is thoroughly un-good. 500 that is = Internal Sever Error = that is bad (hombres).
It is not supposed to happen. Running Linux/Unix are you, should be stable. Need to look at the stack(s)?
OK, It may be a hardware failure (mm, it happens and they’re a b**ch, however you should have triple redundancy, right?)
And you would not have HW-failure twice in a month? The machines just do not operate like that.
Mean Between Hardware Failure? MBHF? You know? For kids? Or are you running them to hard?
