Yes, every 300seconds.

Wrong! Dead wrong. This is NOT an MCM1 file, but one of a set of 11 files that are part of a ARP1 WU download. It is unique (and varying in size, anywhere from 44 to 49MB) to each ARP1 WU...
Each ARP1 WU down load consist of 4 files starting with the ARP1 WU name and and ending in _input, with 1.74KB in size plus 3 ARP1*_input_d01 though_d03 files, all of a size of about 11.xMB, as well as 7 files with 32 random hexadecimal number characters, with 3x in the 650KB range and the rest varying between roughly 12MB and 18MB plus one file in 44-49MB size range.

This is NOT a static MCM1 "master" file that is the same each and every time and for every one...

Than why do I have it on my current computer, which has never seen an ARP WU?

This is the content of "dataset-curatedOvarian_EarlyLate_v1.0.txt", which can be found in every MCM slot dir:

This is not ARP1, it's dataset for the current batch of MCM1 and it's the same file since months, my current copy has beed downloaded the 12th June (I back it up outside the WCG dir and hardlink it back every time BOINC deletes the file, than BOINC just checks the file and skips the download).

Ralf,

That IS the current MCM1 master file -- the "dead giveaway" is that if that is still waiting to download when all the MCM1 .txt files have downloaded no MCM1 tasks start until it has been received!

For some reason, MCM1 master files never seem to have the BOINC option to make them "sticky", so if a system runs out of MCM1 tasks the file gets deleted and has to be fetched again -- unfortunately, this tends to happen a lot when there are download problems.

As link64 said, the master file for SARC1 is a lot larger, but we're still back on Ovarian Cancer at the moment, and these tasks run a lot faster because the data set is smaller and easier to process...

I know I'm re-iterating what link64 said, but you apparently didn't believe it (or what Crystal Pellet said in the post before that); I hope the third time of telling you is the charm, but if you don't believe me either, find that file on one of your systems and delete it, then see what happens to any MCM1 tasks that might be present :-) [Hint: I don't think the client is smart enough to fetch it again once it thinks it has it...]

Cheers - Al.

P.S. -- it is not my intention to give offence, merely to help correct misunderstanding :-)

[Edited to note that Ovarian tasks run a lot faster than Sarcoma tasks...]

I don't really understand, why anyone should run out of MCM work and generate unnecessary downloads on the already overloaded download server just to post a screenshot or log of a download of that file, when everyone crunching MCM can verify in few seconds, that this file is part of MCM and that it is used for every MCM WU, just check the entries for MCM WUs in the client_state.xml:
