Hello Guys,

I need some assistance with troubleshooting this error message that i keep getting after running the program about 2 mins. It doesn't matter what i do/change the error happens about 2 mins into executing the program.

Error message: VI_Error_Alloc Insufficient system resources/ memory

Does Agilent have any 2 mins limit in their VISA call If so how can i disable it ?

Regards,
D

Any chance you are programming via the VISA libraries and you are not closing the session via the viClose call? Or possibly opening many sessions?

hi tsilchia,

Yes, i am programming via VISA libraries over LAN. The only time ViClose is used is when i hit "exit" button on the GUI, otherwise it keeps on collecting data and displays the data to the user.

Under what condition do i get the VI_ERROR_ALLOC error message. In the Visa32.bas the VI_ERROR_ALLOC is defined as follow:

Public Const VI_ERROR_ALLOC As Integer = &HBFFF003C

From what it looks like after two minutes of running the code the error happens at first two lines of code.

status = viOpen(defrm, "TCPIP::192.168.1.45::inst0::INSTR", 0, 0, vi)
        If (status < VI_SUCCESS) Then GoTo visaErrorHandler
.
.
.
.
ErrorHandler:
        ' Display the error message
        MsgBox("*** NonVisaError : " & ErrorToString(), MsgBoxStyle.Exclamation)
        Timer1.Enabled = False
        Exit Sub

VisaErrorHandler:
        Dim strVisaErr As New VB6.FixedLengthString(200)
        Call viStatusDesc(defrm, status, strVisaErr.Value)
        Timer1.Enabled = False
        MsgBox("*** VisaError : " & strVisaErr.Value, MsgBoxStyle.Exclamation, "VISA Error Message")
        Timer1.Enabled = False
        Exit Sub

Could anyone help me out

Thanks
D
