Notification: What Does "Inotify initialization error" Mean?

What is your operating system?

This is a Linux operating system error indicating that there may be a problem with the file system. I don't understand it well enough to know if it's from your local computer or from the mail server, but in either case the error is being passed on to you by Thunderbird, but it's not a Thunderbird error.

Lin,

Thanks for identifying the message.

"This is a Linux operating system error indicating that there may be a problem with the file system"

That is very strange, I'm running Windows 11 Pro 25H2. I don't have a dual boot or a virtual machine, in fact I don't have anything Linux. Maybe it originated on Claranet's mail server?

Alan.

In that case, the error message is generated by the email server indicating a problem on their end. I imagine you aren't the only one being affected by this and they may already be working on it, but you might try contacting Claranet in case they're not yet aware.

OK, I reported the notification to Claranet's exasperating support department and they sent me instructions for installing a Gmail account. I protested and they sent me the following:

Senior engineers have reviewed this issue and have advised that this error will not be originating from our servers. It is most likely being generated by your mail application. No other Claranet users have reported this error. Unfortunately there is no further action Claranet can take regarding this issue. ''''''''''
