Also seeing this behavior on I've been having issues with running out of file descriptors in other apps, though I'm not sure if that's relevant to what's going on here or not I have seen it also on linux Linux turtle 4. Ref Line 74 in c3ad. I have been able to trigger it by switching from one internet connection to another. I think the watch channel is closed and we're stuck in an infinite loop because of it. I've been running this for a few days now and while the CPU usage issue is gone, I've seen the "Log aggregator watch has stopped, respawning it.
I guess there's something that goes bad elsewhere in the log watching state machine and just respawning it again is not sufficient. This change is better than nothing as it gives a landmark in the logs to launch deeper investigations from. Anyone have ideas about what might be going on? I looked at the linked PR but there is not much detail on it.
Does the mtime watcher basically poll large directories for modification of files? I'm experiencing this issue when switching between my home network and my office network. I've used those tools a lot on other projects and switched networks without issues, as I routinely work from home and from the office on the same laptop. Is the mtime watcher the default on 0. Not sure how skaffold is doing it, but you might be onto something there. So something environmental causes it to start happening.
Thanks r2d4 - I'll see if I can pinpoint where the issue is.
I've done some rudimentary debugging fmt. Println in spots I suspect to be problematic and it seems that when this issue starts happening, it's in log. It seems to start thrashing there and receives events seemingly in a tight loop. This matches up with what ajbouh observed too. When I create a watch on pods e. I have the trouble that after exactly 20 minutes, the ResultChan receives infinite messages, but they are all empty.
It is expected. Server will timeout the watch connection, see code. Though I'm not sure why it's 20 mins, it timeout after mins if you didn't change the default configs of your server, because the default MinRequestTimeout is 30 mins. Example code that uses Watcher correctly: This probably matches what I see. Every time this issue starts happening for me, it's when log output from the containers has been idle for a while e.
