      Hi, 

      We have a hard to identify issue here needs your help. One instance's primary node suffered from GlobalLock suddenly arising, consuming out of all the connections. It looks like relative with WiredTiger cache evict problem because at that time the cache usage had reached 95%. This issue happened at 2020-05-18:12:36:45 GMT+8, and I have provided the FTDC data and some logs needed. Please help look into this issue. Thanks!
