We have mongodb cluster with 3 instances. After increase of amount of writes there, WiredTigerLAS.wt become 20Gbs size on all nodes in just few mins. It leaded to out space issue and of course downtime. This is strange, because usually this file have size less then 1,5 GB.
I tried to find in a documentation how to control its size, but no luck. Can you suggest how to limit its size and maybe you know what can cause this situation.
