问题
I have a arch 64bit VPS on digitalocean. I installed gwan and run it in deamon mode. It stopped running every midnight.
Here is the log file

回答1:
This problem does not happen on all platforms and so far all the user reports we received used hypervisors which alter the CPU and OS behavior in erratic and undocumented ways (not to cite the additional bugs they inject into the system).
UPDATE
That new problem for 4-years old code that worked fine so far is a platform issue, for which we have found a workaround, to be published with the next release in a few weeks.
