The channel access gateway used by Mya, cagwops, was locked up for the second time in three days. This time the lockup was preceded by 217 "Virtual circuit unresponsive" errors related to various iocs at 8:48. Nine minutes later there were 45 "Virtual circuit
disconnect" messages before the gateway suspended its main thread and became unresponsive at 8:57. Useful operation seems to have ceased at 8:48. This is a particularly annoying failure mode because if the process crashed altogether it would be restarted automatically.

I restarted the gateway process and noted that over 100,000 signals were connected within a few seconds, so this gateway is getting heavy use. It's possible, if unlikely, that the VM needs more resources.</div>

I'm pretty rusty with IP4 networking - is that a broadcast address? On opsl00 setting my EPICS_CA_ADDR_LIST to that value and then attempting a caget doesn't work, I'm assuming because broadcast addresses can't be routed across subnets perhaps so I would
need to be on a hall host to do this (hence gateways)?</div>

<div class="">I spot checked some random PVs in the archiver, and it looks like the archiver lost channel access to all Hall B PVs yesterday morning around 8:48. Probably need to check the accelerator’s gateways?<br class="">

I’ve never looked at them via wedm. Their IOC hasn’t changed. There was some network work in Hall B a few weeks ago, but I assumed this was a recent change. Marc, when was the last time you saw them on wedm?</div>
