RE: [lwip-users] multi-threaded environment

[Tom C. Barker]

Leon,

The default was 3 and I found that I was not getting any tcp (tcpip)
connections. I found that when I went to set up a timer in 
tcp_timer_needed(void),
it would return void because of the limit of 3 system timeouts. I had one 
timer for arp, one for dhcp fine and one for dhcp coarse. Asking for another
returned null at memp = memp_tab[type]. I set MEMP_NUM_SYS_TIMEOUT to 5
and I began to get my polled tcp (should I say, application) connections.

Does that make sense?

Tom

Could you explain why?

I am not really knowledgable on the sysarch and sockets layers around 
lwIP, as I have merely kept myself focussed on the underlying protocols 
and modules.

Regards,

Leon.
