Potential FIX FEED DOM problem

Hi,

I have been having some problems with the DOM (full book) Market Data - Incremental Refresh on a brokers feeds. I havent yet seen it on any other brokers feeds but others are nowhere near so busy

I understand the feed in question is unfiltered so will have fleeting crossing prices, but i am seeing some attempted deletions of prices not yet placed and stale prices left on the book

I captured a series of FIX messages showing book price updates - it shows an attempt at deleting a quote a couple of message before the quote is added - on this feed this is happening frequently - i can supply more examples if you require

I have scanned the whole FIX feed and this is the first time the query id has been used and it is not referred to in the next 10 mins at least (the segment from my log file)

I have considered that the query is is an old entry and it is merely being re-used but surely i would have seen an initial refresh when i connected that included this query id. See above comment re it not being referred to again

I clear my book onLogon and onLogout, and on market full refresh (which BTW is not documented in your FIX guide) and the messagesd between 22276 & 22279 below are just updates for another symbol which i have omitted for clarity

Here is a FIX segment showing the affected query/feed
