Error 4786 with Windows Service

After my Windows service runs for a few days (sometimes 5, sometimes 3), I'm
getting the following exception in the Event Viewer:

Event Type:    Error
Event Source:    COM+
Event Category:    Unknown
Event ID:    4786
Date:        10/31/2006
Time:        1:29:50 AM
User:        N/A
Computer:    KII-SERV-SQL
Description:
The system has called a custom component and that component has failed and
generated an exception. This indicates a problem with the custom component.
Notify the developer of this component that a failure has occurred and
provide them with the information below.
Component Prog ID: 1[ODBC][Env 45814e8]
Method Name: IDispenserDriver::CreateResource
Process Name: DTSService.exe
Exception: C0000005
Address: 0x04972018
Call Stack:
pvm90sec! + 0x2018
pvm90sec! + 0x2516

I tried looking for more information on the web, but I haven't really found
anything that would explain what's possibly causing the exception. Why it
would fail only after a certain number of days?
Thank you for any help.

The exception is an access violation which appears to be occuring from COM. I
dont know what the IDispenserDriver is so I assume it is something you have
coded.
I found some explanations of the problem here: http://www.eventid.net/display.asp?eventid=4786&eventno=3412&source=COM+&phase=1

It depends on what your actually doing as to what the cause could be. An
access violation is the same as a NullReferenceException in .NET. It can be
be caused by almost anything although in a .NET app it must be a COM interop
as the framework turns them into NRE's when it encounters them.
