Understand why buffer get overflowed running testapp

[Kewei-Lu]

Hi team,

When running testapp under a large number of threads and relatively big size of async_jobs

for example ./testapp -engine qatengine -async_jobs 32 -c 2000 -n 40 rsa2048 -perf.

The system will report *** buffer overflow detected ***: terminated.

Is this from USDM complaining about too much pinned memory, or from libssl for too much ASYNC_WAIT_CTX created?

My hardware setting:
CPU: Xeon 6554S 2 socket
Memory: 502GB

My software setting:
OS: centos 9 stream 6.2.0
QAT driver: QAT OOT driver 1.1.40

Thanks
