Dear all,
I am using ovs 2.14.1 and dpdk 20.08 on CentOS Linux release
8.3.2011 with kernel of 5.10.44. It is observed that there are some error
information about memory in ovs-vswitchd.log

Is there a patch to fix this problem ?
The short answer is that there is probably not enough memory being
pre-allocated in 'other_config:dpdk-socket-mem=x,y' and at some point
you are running out of mbufs. The first thing you should do is increase
the amount of memory and re-test.
These blogs are a few years old, but should help:

thanks!
