Hi Petr,
I have just this morning ran a log collection fro Symantec from the Master and the OC, they had issues trying to recreate the problem, looks like I am working with the USA team so there is a time lag, the files collected are almost 200Mb in size so now have to wait for an ftp site from them where I can upload the files.
I did mention that I had placed the issue on Connect and the engineer did say he had noticed that I was not the only one with the problem, might be worth placing a call, in the mean time if i get anything from them I will let you know.
