Help with error log

[lairgweather]

Hi

Every few days cumulus stops loading data to my website however it is still running on the pc and showing the data,a reboot of the pc fixes this for another few days,there is no anti virus on the dedicated weather pc,just cumulus installed.
here is a copy of some of the log,can anyone help?

thanks

The I/O error 1816 you have had before: https://cumulus.hosiene.co.uk/viewtopic.php?f=13&t=6717

The 11004 error is Windows sockets saying that it can't connect to the server. I guess it's possible that the two errors are related as they are apparently happening at about the same time, but unfortunately Windows isn't giving any more information. As Mark suggested before, I think it will take some kind of process monitor to find out what's happening.

Thanks Steve - yes i did i recall now,i replaced the pc since then.
I will dig deeper

You could perhaps keep an eye on how much memory Cumulus is using, and how many file handles the system is using. It's possible there's a leak somewhere; the tricky part is finding out why it's apparently only happening to you, and what's causing it.
