The error message you're seeing:

 2009/07/23 13:28:10.304 L0 vxiCreateIrqChannel VXI: channel not

established (create_intr_chan)

is coming from vxiCreateIrqChannel(). The error status is being

reported by the ICS 8065. The 8065 is reporting a failure of the

create_intr_chan remote procedure call. Here's the code from the asyn

VXI-11 driver.

    clntStat = clientCall(pvxiPort,  create_intr_chan,
        (const xdrproc_t) xdr_Device_RemoteFunc, (void *) &devRemF,
        (const xdrproc_t) xdr_Device_Error, (void *) &devErr);
    if(clntStat != RPC_SUCCESS) {
        asynPrint(pasynUser,ASYN_TRACE_ERROR,
            "%s vxiCreateIrqChannel (create_intr_chan)%s\n",
            pvxiPort->portName,clnt_sperror(pvxiPort->rpcClient,""));
        xdr_free((const xdrproc_t) xdr_Device_Error, (char *) &devErr);
        clnt_destroy(pvxiPort->rpcClient);
    } else if(devErr.error != VXI_OK) {
        asynPrint(pasynUser,ASYN_TRACE_ERROR,
            "%s vxiCreateIrqChannel %s (create_intr_chan)\n",
            pvxiPort->portName, vxiError(devErr.error));
        xdr_free((const xdrproc_t) xdr_Device_Error, (char *) &devErr);
        clnt_destroy(pvxiPort->rpcClient);
    } else {
        vxiSrqEnable(pvxiPort,1);
        xdr_free((const xdrproc_t) xdr_Device_Error, (char *) &devErr);
        return;
    }

The error message indicates that the remote procedure call itself

succeeded (i.e. that clntStat == RPC_SUCCESS) but that the remote

device (the ICS 8065) reported a failure. My guess is that it has a

limited number of channels available and you've run out after four

restarts.

Have you tried issuing a reset to the ICS 8065 before starting the

IOC? The asyn VXI-11 driver provides reboot commands for the Agilent

E2050 and E5810 devices. Perhaps something similar could be done for

the ICS 8065?

I put these two commands in my st.cmd file:

asynSetTraceMask( "L0",10,0xff)
asynSetTraceIOMask( "L0",10,0x2)

I assume that I did what you suggested. I am not sure what is

traceIOMask=255?

This is what I did:
1. Reboot the gateway,
2. Start IOC.  I get many trace messages.

3. Restart the IOC until it fails. It failed on the fourth

restart. This time I got not one trace message.

4. I repeated the above and again on the fourth restart it failed.

Seems that some resource is being exhausted.

Thanks,
Zen

One suggestion would be to set asynTraceIOMask=2 and traceIOMask=255

for that asynPort in your startup script. Then reboot the IOC until

it fails and see if you can what is different in the traffic.

I am using ICS 8065 Ethernet - GPIB gateway. The soft IOC is built

with EPICS R3.14.9, asyn version 4.11, streamdevice version 2.4.

Sometime when I restart the IOC it dies with the following error:

I don't understand these error messages. I need to understand in

what way the gateway is failing so that I can explain my problem

more intelligently to the tech support at ICS. So, my question is

how to interpret the messages listed above?

Are there other users of the ICS 8065 gateway? Has anyone seen this

problem? If so what is the solution?

Thanks,
Zen
