[AGENT++] Problem when run agentx++win32master process

[Dave White]

Daniel,

I would guess that one (or more) of the SnmpExtension DLL agents that
agentx++win32master loaded did not return a valid handle when a call was made
to its SnmpExtensionInit function (through the variable initFunction).  I
think that the code in ExtensionDLL::init needs to initialize the value of
the local variable eventHandle to zero in case the called routine does not
set the value eventHandle to anything.  I also suggest checking the value
after the call to the SnmpExtensionInit function to insure that the value is
not INVALID_HANDLE_VALUE.  If it is, then it should zero the local
eventHandle variable.  The code in TrapPoller::run is already set up to not
add any event handles that are zero.

For example, try the following:

HANDLE eventHandle = 0;
AsnObjectIdentifier asnOid;
BOOL status = initFunction(0, &eventHandle, &asnOid);
if (eventHandle == INVALID_HANDLE_VALUE)
    eventHandle = 0;


I hope this helps.

Regards,
Dave

Hi Frank and all list members:
  I'm using the agentx++win32master.
Once it run, the error msg below display on the stdout continuously.

20040722.16:33:11: 1884: (2)ERROR  : Wait for traps failed (reason): (6)


I consider the problem occured in the function TrapPoller::run().
when execute the sentence below, the return value is very large.

DWORD status = WaitForMultipleObjects(n+1, eventHandles, FALSE, 10000);


It seems that there is any problem with the TrapPoller.

Any suggestions would be greatly appreciated.
Daniel
