Issue when Executing Simulation in Parallel
Recently I updated my system to Ubuntu 21.10. Then I installed the pre-compiled OpenFOAM v2112 based on the information on the webpage. When I started any case from the tutorials in parallel mode, it diverged rapidly. I've attached the log.simpleFoam from the motorBike case.
In order to overcome of this problem, I changed maxThreadFileBufferSize from 0 to 1e9 in the global controlDict. The motorBike case went smoothly after this.
However, the more complex solvers such as compressibleInterDyMFoam in the sphereDrop setup or the DTCHullMoving setup diverged immediately no matter how I set maxThreadFileBufferSize. I also attached those 2 log files (log.compressibleInterDyMFoam and log.interFoam).
To reproduce this behavior, use Ubuntu 21.10 with motorBike or sphereDrop tutorial. You can check that maxThreadFileBufferSize is set to 0 in $FOAM_ETC/controlDict initially.
Relevant logs and/or images

OpenFOAM version : v2112 Operating system : ubuntu 21.10 Hardware info : Intel(R) Core(TM) i9-10900 CPU @ 2.80GHz Compiler : gcc
- OpenFOAM version : v2112

Partially fixing: I changed maxThreadFileBufferSize from 0 to 1e9 which fixed 1 of the 3 cases.
