Converting iCalendar stream not generated by Notes

We have a Windows 6.5.1 Domino box which has behaved itself very well indeed for years until this morning.

Each time Domino starts it seems fine and then the following appears on the console and the server immediately crashes:-

Converting iCalendar stream not generated by Notes.

Product ID:-//The Horde Project//Horde Application Framework 3.0//EN

Thinking we might have an illegal client install of Kronolith or similar on our network, we isolated the server and started it with the network cable unplugged - same message - same crash.

As far as we can tell, nobody has changed anything on the server and the viral scans come up clean.

Any and all suggestions or help with this one will be warmly apprecaited …

For the record - we moved the server up to R7 and the issue just disappeared - I guess the root cause is still there but the R7 code ignores it …

Last Friday we had the same problem.We have two domino servers in a cluster mode.

Main server crashed with this same message.

Secondary server crashed with the message: PANIC lookuphandle. handle out of range.

We have recovered main server by restoring backup copies and will know proceed to recover the second one.

Any additional information will be appreciated, as I’m afraid, this can happen again.

Thank you,

Maria

Our Domino Server version is 6.5.3

Before rebuilding the secondary server (an isolated cluster member after the crash) I spend some time investigating the problem.

Here is what I found:

There was a message in the mail.box database, this message was an “Accept” to a meeting. The meeting was created by one of our users and one of the attendees was from an outside organization. This attendee answered accepting the meeting and this was the message in the mail.box that crashed the system.

Delete the message from the mail.box, start the server, and that’s it!!

I played with the message, putting it again into mail.box with the service running and: it crashes the system again, so the problem can be reproduced (but I don’t want to J)

This is the source code of the “crashing” message, that causes the problem:
