I'm seeing similar failure:

tst_kconfig.c:62: INFO: Parsing kernel config '/boot/config-3.10.0-1106.el7.cki.s390x'
tst_test.c:1118: INFO: Timeout per run is 0h 05m 00s

acct02.c:141: INFO: ac_ppid != 25608 (25607)
acct02.c:182: FAIL: end of file reached

but I don't get what process is this record from.
I see 3 pids: library, main and 'acct02_helper'. What 'acct02' process
terminated?
