Hello,
I am using OVS 2.3.0 as the switching mechanism for topologies deployed by
mininet. I am creating some stress tests for my application and I was trying to
find how many bridges my testing setup could support. I got up to 4112 bridges
created with mininet (through ovs-vsctl, I think that's what mininet uses). At
this point ovs-vswitchd is producing a core dump at lib/ovs-thread.c in
function ovsthread_key_create():
if (key->index >= MAX_KEYS) {
abort();
}
MAX_KEYS is defined as L1_SIZE * L2_SIZE, so I changed L1_SIZE and L2_SIZE from
1024 to 2048. This way I can reach the number of switches I need. But I'm
worried that I may face other problems along the way because I don't understand
how these values were chosen. So, is there a reason for this value of 1024 or
was it chosen as an "arbitrary larger" value?
Thank you,
Babis Kaidos
