for windows user not rebooting a machine for a week is strange i know !
Ok I was unsure if this was a bug in the output of ps or if the command had really been running that long!
Also, if this a three year old command, maybe it was stuck from a much order version of Webmin that is lacking proper timeouts?

yes for those process but this behavior is continuous even happening today.
This is not a problem that is solved in recent versions.

The next Webmin release will add an option at Webmin Configuration → Ports and Addresses to set the maximum time a sub-process can run for. With that you’ll be able to set an upper limit on the lifetime of these connections.
You did however checked if between a reboot was needed because of updates?
Take care before reboot you have on other location working backup!
