Marc,
<div><br>
</div>
<div>Really?! That’s great, I had my doubts that it helped. Rebooting the ioc is easy if it happens again, however it does trip the GEM detectors so it needs to be coordinated with the counting house. I’m glad it worked.

I can try to reboot the ioc (iocGEMGas), I have messaged the GEM experts for permission since the experiment is running. I am also able to caget the variables on the host computer (adaqsc) or the counting house computers (hadesk8) but not if I go to adaq1,
even if I change the EPICS address list variable. Weird. So perhaps it is a gateway/network issue. I'll try rebooting the ioc as soon as I can coordinate with GEM experts</div>

I have seen this at least once in the past, where the IOC crashed and we had trouble reconnecting. But it had something to do with the accelerator gateway.</div>

There is something odd, because I just tried manually changing a value using a caput and that worked. I have tried restarting the GEM gas monitoring software, the program starts, runs for maybe 30 seconds and then slows to a crawl, then eventually times out.</div>

Just as a check, I restarted the program on the ECAL cRIO to see if that would fix that issue but it did not.</div>
