error while running osrm with shared memory

[rayudu3745]

terminate called after throwing an instance of 'osrm::util::exception' what(): Cannot update the metric to a dataset that does not exist yet.

I'm getting this error while running the osrm with traffic updates
traffic updates happened smoothly for some days and randomly this error pops up
any insights in whats causing this?
