memory leak

[wimfabri]

When you leave the alerts page open in the browser (tested with both chrome and firefox) the memory usage of the browser process keeps growing. version: docker image alerta-web:latest digest: 7f9be380bf07f2bf4a0d49de1ac1a0538054c1bbff0473489a15e0472e598f76 alerta.conf:

You're going to have to provide more info than that if you want me to be able to reproduce the issue. How many alerts are in the database? How many do you have displayed in the web UI per page? How many environments do you have? How many alerts per environment? Does it happen immediately after logging in without you doing anything or does it only start after you click around for a while? For example, clicking on the environment tabs?

How long have you observed the memory leak for? Minutes, hours, days? And the memory never returns to a lower level? It keeps growing indefinitely? Which memory? JS Heap, documents, nodes, listeners? Please include a screenshot of the Performance console that demonstrates the "memory leak". Thanks.

• web UI version: 8.5.0

• CLI version: 8.5.0

To Reproduce Steps to reproduce the behavior:

1. open Alerta main page
2. wait

For web app issues, include any web browser JavaScript console errors: none

Expected behavior memory usage should not keep growing

Screenshots just opened: after 2 hours:

Additional context Add any other context about the problem here. nr of alerts: 512 customers: 4 environments: 12

NOTE: Please provide as much information about your issue as possible. Failure to provide basic details about your specific environment make it impossible to know if an issue has already been fixed, can delay a response and may result in your issue being closed without a resolution.

I'm also seeing high memory and CPU usage in Firefox after cca hour:

number of alerts: 160 (some of them with thousand of duplicates) customers: 3 environments: 3

Alerta UI: 8.4 Alerta API: 8.3.3 Firefox: 90.0.2

I will be happy provide more information for debugging, let me know.
