Depends on how old, but yes.

ping sends and receives. You say you have checked eth_drv_tx_done. So
you have checked for leaks in mbufs used for transmitting. Have you
looked for leaks of mbufs when receiving the ICMP ECHO reply?

This controls the number of mbufs, clusters and memory pool. See
packages/net/tcpip/current/src/ecos/support.c If you want more mbufs,
increase this.
