I am receiving an error in my listserv, that seems to indicate it is an exchange issue.

Insufficient system resources (UsedDiskSpace[C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Queue])

 

I am running on rhel 7.9, with listserv 16.5

Now, of course I could upgrade listserv, but it was doing fine till just the last couple weeks, when this message cropped up.

 

My exchange person doesn’t seem to find anything, so I am wondering if there is something else, on the listserv, that could cause this.

Thanks
