I made a business layer using VB 6.0 sp 5 and Component Services under win2k
sp3, this Dll executes a few MDX querys through a huge OLAP (Analysis
Services 2k sp3) cube using ADOMD as well SQL Querys to a SQL 2k SP 3a
enterprise edition, this environment works fine in production for several
weeks serving about 40,000 MDX querys at day. We are using MDAC 2.8

Our Presentation Layer has been made in ASP pages, formatting all output in
HTML format

But after days working fine, It started to appear an Provider error
'80040e14' in all MDX querys, is not an OLAP issue because reestarting the
server does not fix the problem, when the COM+ application is restarted is
when the problem disappears.

The production server has The Microsoft Debug Diagnostic Tool 1.0 and has
made a User Dump file for this Dll warning us about a First Chance Access
Violation problem in the Dll, I don't know how to found the problem y how to
interpret the Debug File.
