Re: [lwip-users] Errors in LwIP statistics - what do to?

[Elad Yosef]

Hi, I also noticed that when the PBUF has error the whole LwIP stops
working (no pings, nothing)

PBUF
        avail: 20
        used: 1
        max: 13
        err: 1
        alloc_locked: 0
        refresh_locked: 0

How can I debug this issues?
Just increase the amount of buffers or some other idea?

Thanks

Elad
