NSClient++ Help (#1) - NRPE Quirk (#719) - Message List

I'm running an external script check against a windows server via the NRPE listener, but I've been getting issues with "UNKNOWN: Return buffer to small to handle this command." errors.

The debug log shows:

"2011-01-06 11:45:17: debug:include\NSCHelper.cpp:73: String (9867) to long to fit inside buffer(4096) : [wvpmail1a"

However, if I execute the check on the server with "NSClient++.exe -test" then it returns:

check_exch d NSClient++.cpp(1073) Injecting: check_exch: d NSClient++.cpp(1109) Injected Result: OK 'OK' d NSClient++.cpp(1110) Injected Performance Result: OK:OK

Quite happily. So I'm confused as to where all this data that appears to be overflowing the buffer is coming from.

Any suggestions?
