Summary0001576: transport reliability test fails with corrupted message id
DescriptionThe message ID happens to be correspond to hex representations like
A0A0A0A0, which corresponds to the memset we apply to the body of the test messages. So likely one message gets overwritten by another, or a message is only partially copied (and we see the pattern from a previous message).

Regardless, somewhere someone is not copying correctly...
Additional InformationThis can always be reproduced; however, reproducing it may require raising the number of iterations done by the testcase by a factor of 10x to 100x.

I've now also seen a case where a single message is skipped:

Presumably resolved with various previous fixes (server-tc double free and others). At least now irreproducable.
