ping: sendmsg: No buffer space available

[Valorant Brimstone]

I am currently using 3 RYU Controllers, 7 APs and 10 stations which are moving in a random way point and also ping to destination whjich is fixed via the 7 APs.

Connection between APs and Stations is wireless.

All 10 stations are sending ping with -i 0.2 -t 10 continuously to destination and this ping response is also dumped tcpdump top a seperate txt file for each station.

Aftyer about running my  simulation for 1200 seconds it generates an error in each xterm of my station"ping: sendmsg: No buffer space available"

Kindly provide suggestions/solution to this problem I am facing.
I am running my simulation on a VM.
