# 2251 Shutting Down a DBISAM Database Server That Has Defined Triggers Causes AV

I'm getting a crash when I stop my server without first stopping my client. It only occurs when there are memory table operations occurring on both the client side and in the server (ie. in a server procedure call). Similarly, BeforeUpdateTrigger must be registered, although it isn't called.

See attachment.

1. Create a database directory c:\Artful Ledgers\FixedAssets
2. in the server project, uncomment the AddServerDatabase line.
3. run the server project
4. run the client project
5. close the server
6. observe crash

Comments

The issue was caused by the triggers trying to free a trigger callback object after it was already freed by the engine.

Resolution

Fixed Problem on 1/2/2008 in version 4.26 build 1
