How reliable is your network between their system and yours? Are there
any load balancing devices or other network magic in the way that could
potentially be misconfigured?
That gives me a few new places to hunt down the issue, thanks.
Packet sniffing will answer the question "was there any evidence of a
request", and would probably be the least invasive way of measuring
this. It's always useful to see what the network is actually doing,
rather than what you think it's doing.
Definitely - I've decided to bite the bullet and run tshark in the
background, hopefully that will turn up some new information. Debugging
an error which happens at random a few times a month is an interesting
challenge!
