1. Describe your incident:
Graylog webpage is very laggy, widgets fail to load.

2. Describe your environment:

  • OS Information: RHEL 9 64GB Memory, 16CPU running in a Hyper-V cluster

  • Package Version: 6.1

  • Service logs, configurations, and environment variables:

2025-06-10T14:55:09.061-04:00 INFO [OpensearchProcessImpl] [2025-06-10T14:55:09,060][WARN ][o.o.s.b.SearchBackpressureService] [graylog2.local] [monitor_only mode] cancelling task [2776] due to high resource consumption [heap usage exceeded [1.3gb >= 1gb]]

3. What steps have you already taken to try and solve the problem?
Increased Heap sizes from 2g to 8g to 16g

2

Icreased the heap of what? Because both opensearch and graylog have seperate heap settings. Also are you using datanode?

3

So yes, I changed the opensearch_heap = 8g and the -XMs8g

And I am using version 6.1 which uses datanode.

Update: Still receiving the error and have around 500 devices reporting logs. Mainly Windows/GELF and Syslog from network switches. The web interface is also extremely slow and timeout errors happen frequently.
