time_limit is not respected

[mzy2240]

Recently I found when solving MIP, using set_time_limit_sec to set time limit does not strictly enforce the time limit. For example, right now I am running an optimization with time_limit set as 900 seconds, it is still running now after half hour. Did not encounter the same issue in COPT or AmplNLWriter-compatible solvers.

Do you have the log so we can see where it got stuck?

Do you have an MPS that replicates the issue? Otherwise I will close in favor of the upstream issues.

Closing because this is not a bug in HiGHS.jl.
