[Spread-users] spread abort after Deliver_packet: sequence error

[Jonathan Stanton]

This error is a "must not occur" situation, which is why Spread kills itself with a 
fatal error message. So at some level it is definitely a Spread bug. 

There are two main sources for this type of error:

1) a memory corruption problem, so the value stored in the field is corrupt.
2) a protocol bug where the spread code has a logic error.

Besides having high amounts of UDP traffic (I assume the extra traffic is not 
going to the Spread port numbers) is there anything else interesting about your 
setup?

Did you notice any other messages in teh Spread log that appeared unusual or 
occured in the last few seconds before the crash?

Does the crash occur often? If so how often?

Thanks,

Jonathan
