Ever since I built kernel v2.2.16 with SMP support I have been getting this message in my system log: recvmsg bug: copied 0 seq 93F7B7E The seq number varies from message to message. I get this problem when running the DistributedNet RC5 client. The problem is seen more frequently when running the client with multiple threads. I have been using this same DistributedNet binary since February (with UP kernels) and have seen no problems until now. I've searched the mailing list archives and seen several posts inquiring about this message. What I haven't seen is a solution to this situation. Can someone tell me how to get around this problem? I'll be happy to provides any additional info needed.
