pm2 logs don't update live unless I do "pm2 update" or "pm2 restart"

What's going wrong?

I'm running multiple applications using pm2. For most of those applications, I can view the logs update live. For a few, the neither the live logs displayed with "pm2 logs" nor the corresponding log file update. They only update after performing a "pm2 restart" of the process or when doing "pm2 update". I tried the solutions in an old issue from 2018 (https://github.com/Unitech/pm2/issues/3434), but none of them worked.

How could we reproduce this issue?

I'm not sure what could be causing this issue. The only difference I can visibly see between processes is that the ones not updating are using a lot of memory (> 500MB)

Supporting information

I'm using:

• pm2 version 5.3.1.
• node version v18.19.1
• Ubuntu SMP on AWS.

# Run the following commands
$ pm2 report

I've continued to monitor the pm2 logs output and it seems to be updating approximately every 15 minutes.
