Empty hash in response

[masukevich]

Hello!

Any advice, or further info on the following issue, would be much appreciated.

We are using Ouimeaux server through REST API calls inside Ruby on Rails application. Our network contains several Wemo devices, Ouimeaux works with them flawlessly - we get non-empty hash responses, and we can control the devices. But, as Ouimeaux uptime reaches about 2-3 days, with no changes to network configuration (actually, no changes at all to anything), Ouimeaux starts to return empty hashes for same devices. There are no errors in logs, even in debug mode.

Maybe you could kindly give and advice of what to try next in this situation, or provide any insight on what could cause this.

Thank you.
