ERROR: Inotify-Related Issues in Pods

If your pods experience errors related to inotify limits, you may see logs like the following:

"ts"="2025-03-24 05:09:43.012"|"l"="error"|"m"="failed to create log watcher"|"lt"="A"|"err"="too many open files"|"ct"="f5-coremond"|"v"="1.0"

Cause: This issue occurs when the system’s inotify limits are too low, restricting the number of files and directories that can be monitored.

FIX:

This issue can be resolved by increasing the inotify limits (max_user_watches, max_user_instances and max_queued_events). We recommend updating these parameters at the host level so the configuration persists across reboots. The following example shows the sample configuration.

1. To increase inotify limits, update the following kernel parameters.

   echo "fs.inotify.max_user_watches=1048576" | sudo tee -a /etc/sysctl.conf 
   echo "fs.inotify.max_user_instances=8192" | sudo tee -a /etc/sysctl.conf
   echo "fs.inotify.max_queued_events=65536" | sudo tee -a /etc/sysctl.conf
   

2. After updating the configuration, reload the kernel parameters with the following command.

   sudo sysctl -p
   

This will ensure that your system has higher inotify limits to accommodate your workload.
