Can anyone tell me if they've seen this kind of error in their Meteohub? I'm running v4.4a and I saw this in the system log. Thanks.

That's a
segmentation fault, which means the software was trying to access or write something to memory and had a problem (either the memory address it tried to access is restricted, or there was a problem with the memory.)
Are you running an NSLU2- or x86-based system?
I haven't seen any such entries in my NSLU2 4.4a system log since upgrading the day it was released.

I'm running on a eBox-3300. I've not noticed this before.
So either this is a software problem or a problem with the RAM it seems, correct?

I guess it is a software bug. Which version of Meteohub are you running?
As it just affects the "alarm" program that is responsible to feed alarm messages to the "alarm log" and to send email notifications on this, it is not mission critical. However, I would like to fix this any way.

Could you please post a screen dump of your alarm settings ("setup push services" page) and your "alarm log"?

Here is the image. The alarm log only contained that single alarm entry and I do not have anymore alarms in the log.

I'm not sure if this is related, but about two weeks ago my unit (ebox-3300) gave me a "floating point error" and the Linux OS would not perform CP or MV commands at all. Some software was kept running, but other pieces did not function. I have to reboot the unit when this occurs.

ok, so chances that it is a hw problem might have increased. I will try to reproduce the segfault on my rig. stay tuned...
