Perhaps it's just a tunning problem. How is defined MEMP_NUM_SYS_TIMEOUT in your lwipopts.h? Try to add it +10 (large to be sure) and retest. I you always got the problem, check if in your application you directly use sys_timeout. Else, there is a sys_timeout for PPP, DHCP(2), AUTOIP(1) IGMP, SNMP(0/1), ARP, IP, and TCP. If you test with LWIP_STATS=1 and MEMP_STATS=1, you could see what is the max value for "SYS_TIMEOUT" if you call stats_display(). ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr ==================================== P Avant d'imprimer, penser à l'environnement
