Hi,
Below is part of my startup.conf.
The default heapsize is 512M, so I set 2G heapsize for 4 CPU cores.
But it does not work, nothing changed, any ideas?
main-core 1
## Set logical CPU core(s) where worker threads are running
corelist-workers 2-3
heapsize { 2G }
Regards

Hi,
You should increase heap size. In startup.conf, heapsize 1g or something like
that.
When running in multi-core environment, vpp definitely need more memory,
because some global variables have to be expanded to have multiple copies – per
worker thread. F.g., Interface Counters, Error counters …

Subject: [vpp-dev] show trace caused "out of memory"
Hi all,
When we only use one CPU core, the cmd "show trace max 5000" works well.
But it will crash when we use four CPU cores because of "out of memory".
Below are some information, any guides?
