Hello,

 

I have a question about mbuf po= ol memory allocation. When I have my machine freshly started, it usually wo= rks flawless to run testpmd. But after a few days uptime sometimes the allo= cation of the mbuf pool fails. Currently I get the error "Not enough space".

What could be the reason behind= this that it works after a reboot, but not after a few days uptime?

According to the windows taskma= nager there is still 32.8 GB free memory, and only 30.3 GB is currently use= d.
