日志文件中奇怪的 Mongo DB 写锁值

Question

我的 Mongo DB 日志文件中出现了一些奇怪的写锁值：

Wed Mar 19 10:03:47.007 [snapshotthread] cpu: elapsed:4010  writelock: 0%
Wed Mar 19 10:03:51.007 [snapshotthread] cpu: elapsed:4000  writelock: 0%
Wed Mar 19 10:03:55.012 [snapshotthread] cpu: elapsed:4005  writelock: 0%
Wed Mar 19 10:03:59.028 [snapshotthread] cpu: elapsed:4015  writelock: 385%
Wed Mar 19 10:04:03.042 [snapshotthread] cpu: elapsed:4014  writelock: -2147483648%
Wed Mar 19 10:04:07.045 [snapshotthread] cpu: elapsed:4003  writelock: 0%

这是“正常”现象吗？或者我应该担心吗？

Answer 1
