First of all, thanx for all the response (including the off-list response from Macromedia).
It turns out I hadn't applied one fix from the release notes http://www.macromedia.com/support/flashcom/releasenotes/mx/rn_mx.html Apparently this can cause a lockup of a shared file object when there are a lot of people chatting, which would cause FlashCom to crash. A crash like that has happened twice, once on Saturday during testing, once earlier today. The first time nothing really bad happened, server was restarted and everything worked again. But today, during the crash the FCChat.chat_fc.history.fso file was damaged. This resulted in FlashCom crashing whenever 6 lines were entered in the chat (I presume because after 6 lines the log cache is flushed to the disk). After renaming the log file FlashCom stayed up. So about an hour ago I restarted the service for, hopefully, the last time to implement all the suggested fixes and rthe change from the release notes. Since then it has been stable, and I hope it will remain that way.
