Hey Stanislav,
We have configured heap-size on .conf as 7GB and it is free.
Below are the prints:
ram memory:
root@5495e5b86e58:/home/Immaculate/Oct12/vpp# free -h
total used free shared buff/cache
available
Mem: 7.6G 2.1G 139M 21M 5.4G
5.2G
Swap: 7.8G 112M 7.6G
heap memory:
DBGvpp# show memory main-heap
Thread 0 vpp_main
base 0x7ffe33ab5000, size 7g, locked, unmap-on-destroy, name 'main heap'
page stats: page-size 4K, total 1835008, mapped 97293, not-mapped 3,
unknown 1737712
numa 0: 97293 pages, 380.05m bytes
total: 6.99G, used: 103.44M, free: 6.89G, trimmable: 6.89G
