GEOEVENT "Buffer Overflow Channel" Error

MANESK

Hi,

I'm fetching data using "Poll an External Website for JSON". For few days it was fine and recently i'm getting the error message
as "Input 'JSONurlPoll_input' experienced a buffer overflow on channel ''. It cannot parse the data as fast as the data is coming in. Some data was lost.".

What is the issue and how to fix it. Screenshot attached for your reference.Kindly suggest.

Hi @MANESK - There's a few things you could try here:

1. If you can afford it, try pre-filtering the data so that you're only bringing in the data that matters, thereby shrinking the payload.

2. You could try increasing the polling interval to give GeoEvent Server more time to process the incoming records as events.

3. You could consider increasing the input buffer capacity. By default its 20MB but increasing it might prevent the overflow from happening for a time. This is a setting in GeoEvent Manager > site > settings. Check out this page.

4. It could be worth checking out how much RAM is available on the machine where GeoEvent Server is running and whether or not GeoEvent Server is having to compete with other processes that are also consuming RAM.
