[lwip-users] MEM TCP_MSG used: 65535

[David Shmelzer]

Hi,

I have a problem where lwip stops responding after an hour or so and the
STATS show the following:

MEM TCP_MSG  
avail: 8
used: 65535
max: 3
err: 0

also

PBUF
avail: 10
used: 1
max: 3
err: 7

Any ideas how the used value of TCP_MSG went negative?

The network traffic that lwip has to respond to is a continuous 1s
interval ping, my custom packet and the occasional broadcast packet from
our office LAN which I have no idea what it contains.

Thx,
Dave
