Informix ODBC failing in IIS application
When running IIS in multi-threading mode, the informix ODBC driver is causing a access violation and dying. Has anyone seen this? I would appreciate any suggestions to solve this... Thanks in advance, Neil Pengelly, Disus Inc. neil@disus.com Here are the details: (Note, the problem doesn't occur when IIS is put into debug mode (single-threaded), so this leads me to believe this is a problem related to threading in the ODBC driver). ***** Activity prior to crash ***** dule Load: C:\\PROGRAM FILES\\COMMON FILES\\SYSTEM\\OLE DB\\msdasqlr.dll (symbol loading deferred) Module Load: C:\\WINNT\\SYSTEM32\\mswstr10.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\iclit09b.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\iregt07b.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\irrgt09a.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\igl4n304.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\irclt09b.dll (symbol loading deferred) Module Load: C:\\WINNT\\SYSTEM32\\ctl3d32.dll (symbol loading deferred) Module Load: C:\\WINNT\\SYSTEM32\\odbccp32.dll (symbol loading deferred) Thread Create: Process=0, Thread=47 Module Load: C:\\INFORMIX\\BIN\\igo4n304.dll (symbol loading deferred) Module Unload: C:\\INFORMIX\\BIN\\igo4n304.dll Thread Create: Process=0, Thread=48 Thread Create: Process=0, Thread=49 Module Load: C:\\PROGRAM FILES\\COMMON FILES\\SYSTEM\\ADO\\msadrh15.dll (symbol loading deferred) Module Load: C:\\INFORMIX\\BIN\\igo4n304.dll (symbol loading deferred) Module Unload: C:\\INFORMIX\\BIN\\igo4n304.dll First chance exception c0000005 (Access Violation) occurred Thread stopped.

The actual dll name(s) appear in the right-most column of the stack list. If this is a file you created, you can get symbolic information for it by compiling it as a debug file and EM will be able to read it. If this file is from another manufacturer or vendor, contact the vendor to get symbol files for the files in question.By getting the symbolic information, you can trouble shoot the problem even further by seeing which function calls were being used when the system crashed. NOTE: The function(s) that are unresolved may not be in the faulting thread, but you still want to obtain symbols for future debugs.***** The following third party modules were running in the process's memory space: C:\\Disus\\MyControl.dll MYCONTROL.DLL] Company Name: Test.
