[ other examples snipped ] Not sure if the packet truncated messages are ultimately related to the crash, but they suggest that the code in pbuf.c isn't setup to handle either TSO (TCP segmentation offload) or LRO/GRO (Large Receive/Generic Receive Offload) on your system. So, at the downside if increasing the CPU utilization on your system, you could disable either/both of those optimizations (TSO has been around for many years, LRO/GRO have arrived in the last couple) and see if that improves stability. That, or, based on some grepping for 8232, you could go into ./globals-defines.h and ./globals.core.c and re-educate the code. rick jones _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop
