[TT-4087] Possible memory leak or non present cleanup

[diegobernardes]

Branch/Environment/Version

• Branch/Version: 3.1.0
• Environment: On-prem

Describe the bug

Y-axis is % of memory used at the Docker container. The memory usage is simply way too strange. It increases rapidly and it does not return to any healthy level after it. One of the containers jumped from 27% to 99% of memory utilization.

If I do a restart of the containers they simply stay on a healthy level once again with around 20-30% memory utilization with the same throughput.

Hi!

Thank you a lot for reporting!

How many APIs do you have?
Does it memory of the gateway or the dashboard?
Can you attach tyk.conf and gateway logs? (feel free to send them to support@tyk.io if there is smth confidential).

[diegobernardes]

Hi,

It's the gateway. I'll send the information to support@tyk.io.

Hi @diegobernardes,

I believe this is fixed in Tyk 5 per the linked issue #3754 and will close the ticket accordingly.
If you can still reproduce this in 5.x please re-open the ticket and we can look again.

Thank you for supporting Tyk!
