Installed is DBISAM ODBC 3.24 on Windows Server 2003 SP2 with IIS6.  The website has been build in regular ASP.

Since a while the website hangs unpredictably on random locations. Looked in the event-report: no answers. Installed Microsoft's DebugDiag: problem lies
with DBISAM:

In w3wp__PID__304__Date__04_27_2009__Time_09_34_29AM__109__Second_Chance_Exception_C0000005.dmp the assembly instruction at
dbisamod+6321 in C:\WINDOWS\system32\dbisamod.dll from Elevate Software has caused an access violation exception (0xC0000005) when trying to
write to memory location 0x029e0c00

Has anyone got an idea as to what is going on here? Or, better, what I can do about it?
