I have always had a problem where I get a fetchmail error message every so often. This became more regular so I changed the mail collection to every 15 minutes but the problem came back so I changed mail collection to every 30 minutes. This has been fine until last week I now get the error every time the server connects for mail collection. I know the error is reported as nothing to worry about, but why is it getting and worse.
The error is:
fetchmail: another foreground fetchmail is running at 23021
