[dpdk-dev] very high VIRT memory usage

Hi all,
I upgraded an old DPDK-based app which was using DPDK 17.11 to latest DPDK
20.05 and I noticed that if I look  at "top" I see that the VIRT memory
taken by my application is now 256.1GB while before it was <1GB.

I've seen this same behavior with also "testpmd" example... is this a known
issue with latest DPDK versions?
Can I tweak some setting to have VIRT memory usage more or less similar to
RSS ?

I forgot to add I'm working on Linux, Centos7

Thanks,
Francesco Montorsi
