On our AMCC 405EP boards, we had problems when CFG_RX_ETH_BUFFER was greater than or equal to 32. Our boards work fine with this parameter set to 31.
I had reported this issue in the mail list and exchanged a couple mail with Stefan but did not have time to investigate to root cause.
Best regards, Tolunay

Yes, the behaviour changes with the network topology. On some switch, timeout occurs more often, but in the manufacturing center, we have an "island network", and it seems that the problem have not be reproduced.
Do you have lot's of broadcasts on your "main" network connection? Please try to increase the number of rx-packets again. For example:
#define CFG_RX_ETH_BUFFER 256
And please let me know if this helped. Thanks.
Best regards, Stefan
