The mobilink service hit error like:
E. 2015-01-29 15:48:28. <26912> [-10117] Stream Error: Internal error: DelayExpired: _state.http_state returned 0.
And then many Sync Failure coming, till more DelayExpired coming and most of the Sync requests failed.
I guess this error come from too many concurrent requests, so I adjusted the workers number in mobilink start script, but did not solve it.
Need help with it, thx
