# This is to see whether "GitHub Actions xx lost communication with the server" was caused
# by maxtr = huge(maxtr) - 1_IK. We suspect this because the error occurs with IK = i8
# and IK = i4 for all solvers when testdim = small, but not with IK = i2 at all.
# Update 20240422: The error does not occur any more after the update. WHY? Does this imply
# INFINITE CYCLING in the code?
# update 20250816: First, server shutdown is observed on LINCOA/BOBYQA small tests with IK = i4.
# Is this the same issue as before? Second, in the current workflow (and many others), the
# definition of IK changes daily. If this issue is related to IK, it will not be observed every day.
