Hi all,
We've run into a snag passing data between our Earthworm production servers and I'm interested in hearing how others are currently doing this. We seem to have outgrown ringtocoax and coaxtoring, and import/export pairs and seedlink seem like good options, but there might be other solutions.
The issue is that we're seeing gaps in our the waveservers and seedlink server on one of our production servers. The server in question is currently running two instances using Earthworm 7.9. The first instance runs 17 waveservers with a total of 1054 wavetanks. The second instance runs a seedlink server which is our feed to IRIS. Data are fed to both Earthworm instances via coaxtoring modules on a tracewire.
Until recently, this has been fine with a few limited issues. The problem seems to be rooted in our reliance on the tracewire to move all of our data. The server, though powerful, seems to have become too busy to collect the UDP packets in a timely fashion. This seems to be confirmed as the gaps disappear after several of the waveserver modules are stopped.
