Understanding an error in my code

I have written a piece of software in Delhpi v5 using MySQL as a backend database.

Im writing errors to a standard text file. 99% of the time the app works fine, but every now and then i get the following error

Error:
Time - 05/01/2006 18:00:24,
Procedure when errored - GetNumberOfInMsgs :
Error Msg - Access violation at address 4BDECBAA
in module 'IDAPI32.DLL'. Read of
address CCCCCCDC

I realise that the 'IDAPI32.DLL' is to do with the BDE. Does this type of error mean anything to anyone?? is it something obvious that im doing wrong??

Any help would be appreciated !!

Thanks

without seeing your code there's no way we can help.
such error can mean lots of things, for example database too busy, database
not available. code-wise, check that you always close the connection.
also, check that other programs are not using the database in the same time.
worst case, if you say it usually works, just catch this error and if it happens try
running the same code again.
