Hey, I’ve found that job will throw “java.io.IOException: Insufficient number of network buffers: required 51, but only 1 available” after job retstart, and I’ve observed TM use much more network buffers than before. My internal branch is under 1.10.0 can easily reproduce, but I use 1.12.0 doesn’t have this issue. I Think maybe was already fixed after some PR, I'm curious about what can lead to this problem?
Best. YuFei.
