Version-Release number of selected component (if applicable):
1.35.6-29614.copr.7895a9d7e2.fc34

How reproducible:
not sure, the test is quite long, we've seen the crash just twice so far

Steps to Reproduce:
1. test=dhcp-timeout_infinity; a=0; while ./test_run.sh $test; do :;((a++)); echo "ATTEMPT $a"; if [ $a -eq 100 ]; then break; fi ; done

Actual results:
no crash

Expected results:
