Another app is currently holding the xtables lock. Perhaps you want to use the -w option?

Hi! For the last few months, I've been receiving this cron notice intermittently. I am not clear what it is referring to or how to resolve it.

I presume it is related to CSF, but searching here and the webs shows the error message related to many other apps. I've found nothing specific to this on the CSF forums. I've looked in the source of /usr/sbin/csf and didn't not find this error message.

Any advice on how to track down this issue and resolution?

I've been getting the notice for several months. At least since CSF v10.07. It has since been upgraded six times to v10.13. And restarted many, many times.

The other threads suggest update and restart, but that hasn't worked.

How do I determine which processes are locking this file and its current status?
