And now.  I have two questions
1.if this error exist,will all trace and jvm metric be lost?
2.if there some msg in server logs just 
like:"org.apache.skywalking.oap.server.receiver.trace.provider.handler.v8.grpc.TraceSegmentReportServiceHandler
 - 86 [grpcServerPool-1-thread-7] ERROR [] - CANCELLED: cancelled before 
receiving half close
io.grpc.StatusRuntimeException: CANCELLED: cancelled before receiving half 
close"
will this make trace or jvm metrics be lost?


中文解释一下:我现在线上100多台机器,就会经常出现某些实例机器是好的,但是就会经常出现机器trace指标或者jvm指标丢失后就完全不会再出现,除非重启服务,我上面列举的这两个情况会导致我预见的这种情况么?
