I have a web direct app that runs fine when opened by 1 person but crashes when someone else try's to access it. We have 200 license connections so this should be able to do this. Full error starts with

"[webdirect] (admin [fmwebdirect])" is modifying this record. You cannot use this record until, "[webdirect] (admin [fmwebdirect]) is finished. 

A record lock--and that's what the error message indicates--ought not to crash the system.  Please report to FileMaker, Inc.

 

That said, 50 is the limit on WebDirect connections.  You have 200 concurrent connections?  Hope you have a lot of FIleMaker GO users.
