A server error has occurred

[Pedro]

I often see the message 'A server error has occurred' appear in a pop-up window. Most often it pops up when I click on a link that takes me to another Mango page, but sometimes it occurs on its own, when I have not done anything on the page. Most often I see it on a graphics page, but that's probably because that's the page I have open most often.

When I check ma.log, I don't see any log entries at all around the times these errors occur. Since I'm on a slow ISP with high latency, I suspect it is a dojo timeout error, or a catch-all javascript error. Could it be caused when the socket closes? Can we please get more clarity as to the possible causes of these errors, or increase the timeout if that is the cause? Ideally, if this is a "no response received" issue, then the message should report "no response" rather than blaming the server.

I often get on the data_point_edit.shtm page and the events.shtm page, but that is not in a pop-up window, and looks quite different:

Thanks for your help.

I get this error a lot when a system has generated a large number of alarms (thousands). Purging the alarms stops the error. You can delete all the events at once by entering:

delete from events

in the SQL console.

Which error do you get a lot? the Timeout error? Does it make a difference if the alarms are acknowledged, or do they have to be purged?

Do you ever get the 'A server error has occurred' pop-up dialog?

Thanks.
