[lwip-users] help! a problem about using semaphore

[Wang Zheng]

hi all,

I met the following problem in using lwip1.1.0 which is base of my embeded http server.

 

phenomena:
When I fresh the network frequently,there is a error which is "the semaphore has been deleted".
I traced the error and found every time the error occur when call
TCP_EVENT_SENT(pcb, pcb->acked, err), line 334 in "tcp_in.c".  

 

question:
Is there anybody has ever met the same problem ?
Is there anybody can give me some advice to find the reason of the promble?

 

Thanks.
