mdhfiz is on a distinguished road
Initially, I was running a solver (laminarBuoyantPimpleSMOKE - a laminarSMOKE solver) in parallel and it ran just fine so I left it overnight and found this error on the next morning:

Code:
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigFpe::sigHandler(int) at ??:?
#2  ? in "/lib64/libpthread.so.0"
#3  log in "/lib64/libm.so.6"
#4  ? at ??:?
#5  ? at ??:?
#6  __libc_start_main in "/lib64/libc.so.6"
#7  ? at /home/abuild/rpmbuild/BUILD/glibc-2.26/csu/../sysdeps/x86_64/start.S:122
Floating point exception (core dumped)
I read in one of the threads it could be because of parallel issue so I ran the similar solver in serial, it ran for a quite a while but alas, I got the same error:

Code:
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigFpe::sigHandler(int) at ??:?
#2  ? in "/lib64/libpthread.so.0"
#3  log in "/lib64/libm.so.6"
#4  ? at ??:?
#5  ? at ??:?
#6  __libc_start_main in "/lib64/libc.so.6"
#7  ? at /home/abuild/rpmbuild/BUILD/glibc-2.26/csu/../sysdeps/x86_64/start.S:122
Floating point exception (core dumped)
What seems to go wrong in the running process?

Side Note: I've listed my *relevant* files (incl. 0 folder) for reference.

Update

I've managed to run the case successfully. The problem was that U was defined in z direction so I changed it to y direction. Error still persists here though. After that I changed the boundary conditions and use pressureInletOutletVelocity for left and right boundary (making a new set of faces) and after that I managed to run it both in parallel and serial!
