I am solving a MILP model using CPLEX 12.8.0, but CPLEX exceeds the time limit on some test instances. More specifically, I set the time limit for 30 minutes using the cplex.setParam(IloCplex::TiLim, 1800) command, but in some instances, CPLEX runs for over 2 hours.

I have faced a similar bug in Gurobi for a few times, but only for my large instances. In those instances, the time for "presolve" was too large, that made the total time larger than the specified limit.

That may be related to the "presolve" phase of the optimization procedure. In large instances, the time for "presolve" may be too large, that makes the total time larger than the specified time-limit.
If that is the case, you can set the presolve parameter to zero, so that CPLEX does not perform a presolve on your instances. The following link is useful to perform that:
https://www.ibm.com/support/knowledgecenter/en/SS9UKU_12.6.1/com.ibm.cplex.zos.help/CPLEX/Parameters/topics/PreInd.html
Also, if you don't want to eliminate the presolve totally, you can limit the number of passes it performs. For that, you can find the parameter in the following link:
https://www.ibm.com/support/knowledgecenter/SSSA5P_12.6.1/ilog.odms.cplex.help/CPLEX/Parameters/topics/PrePass.html
