[lwip-users] how to debug MEMP_OVERFLOW_CHECK

Hi - I'm using the 1.3.2 sockets api, and am binding and then listening on a 
port, then accepting new TCP connections, writing a short message to them and 
closing them in a loop.  This works OK for a few (4) connections, and then I 
was starting to see some failures.  I turned on MEMP_OVERFLOW_CHECK, set at 2, 
and it's catching some overflows.

Is there a common cause of this kind of problem?  Am I likely to have something 
mis-configured in lwipopts.h, or is the cause probably elsewhere?  Thanks for 
any hints on where/how to debug this.
