SYMPTOMS
When you call a COM object very frequently (that is, more than 10 times per second) in an environment that includes the following:
 * A BizTalk server that is using Windows 2000 Server Service Pack 2 and that is running orchestration processes
 * A COM+ application server that is using Windows 2000 Server Service Pack 1 and that is running multiple COM applications, each of which is using the DB2OLEDB Provider
 * A SQL server that is using Windows 2000 Server Service Pack 1

the server may stop responding (hang). A debug of the hang may show a stack trace that resembles the following: Access violation - code c0000005 (!!! second chance !!!) eax=0104e438 ebx=00000000 ecx=00000135 edx=00000001 esi=00000135 edi=0104e458 eip=7801888c esp=0104e3a8 ebp=0104e408 iopl=0        nv up ei pl zr na po nc cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000 efl=00010246 MSVCRT!_wchdir+56: 7801888c 8b01            mov     eax,[ecx] ds:0023:00000135=???????? 0:010> kvn 00 0104e408 7520363a 00000135 00000000 7522f090 MSVCRT!_wchdir+0x56 01 0104e444 7a11788b 0104e458 00000001 05ccb008 MSEIDRDA!DRDAFreeStmt+0x7a (FPO: [Non-Fpo]) 02 0104e45c 7a1572b5 05cf8bc0 00000135 00000001 db2oledb!sqlFreeStmt+0x2b (FPO: [3,2,1]) 03 0104e470 7a1564a0 05ccb008 05ccb008 0104e4b8 db2oledb!CODBSchemaRowsetProcedures__CleanUpProcedureInfo+0x35 (FPO: [0,0,1]) 04 0104e488 7a1563c8 05accedc 7a13c84e 00000001 db2oledb!CODBSchemaRowsetPrimaryKeys__~CODBSchemaRowsetPrimaryKeys+0x30 (FPO: [0,4,1]) 05 0104e490 7a13c84e 00000001 00000000 05accedc db2oledb!CODBSchemaRowsetPrimaryKeys__`vector deleting destructor'+0x8 (FPO: [1,0,1]) 06 0104e4c0 7a121f4b 05acced0 00000000 00000000 db2oledb!CODBRowset__FinalRelease+0xde (FPO: [EBP 0x0104e4c4] [0,6,4]) 07 0104e4f0 7a12226d 05acced0 1f35a180 05accf20 db2oledb!ATL__CComPolyObject__~CComPolyObject+0 x3b (FPO: [0,6,3]) 08 0104e4f8 1f35a180 05accf20 068589c0 068589b8 db2oledb!ATL__CComContainedObject__Release+0xd (FPO: [1,0,0]) 09 0104e56c 1f35a432 068589b8 068cd8d0 068c5fc0 msadce!updGetKeyFields+0x20b (FPO: [Non-Fpo]) 0a 0104e58c 1f35b08f 068589b8 068cd8b0 068cd8b0 msadce!updGetKeys+0x39 (FPO: [Non-Fpo]) 0b 0104e5ac 1f35b10b 00000001 068cd8b0 00000007
