Jean-David,

Whilst I can't give you a one-liner as to how to solve that, I will point out that beta12 appears to have been Computing for Clean Water -- I've just spent a happy half hour or so digging through the old beta threads to try to find which it was! And that was quite a time ago, wasn't it!

Off-hand, I can think of two possibilities, both of which relate to how old the offending files might be. The first is that there's something strange about checksums for those particular files (version?) or that the files are corrupt/no longer exist. The other is that the files listed in your client_state.xml file for WCG don't quite tally with what's in the projects folder. I must point out that this is not based on first-hand experience, so it could be something else completely!

A reset might resolve this (with a little care about work buffers...) - however, there may be a less drastic solution depending on circumstances, but that's a hands-on situation, not suitable for a remote diagnostic.

I don't know whether this has been of any help (probably not!) But I reckoned someone ought to say something! And as for where you should've posted it, as a "generic" question it was either here or the BOINC Agent forum, I'd guess...

Good luck sorting it out - Al.

[Edited to fix typos.]

I do not know if it happens every time or not. What happens if I just delete those files? If they are not needed, they will be gone, and if they are needed, will they not just be downloaded again?

I cannot replace my boinc client until EPEL does it, and I do not think they will ever do it. I am currently running

boinc-client-7.2.33-3.git1994cc8.el6.x86_64
boinc-manager-7.2.33-3.git1994cc8.el6.x86_64

What file is that? Most, if not all, of the files are over a year old and do not correspond to tasks that are currently being issued.

I am running Red Hat Enterprise Linux 6.10 at the moment, and have RHEL8 on a thumb drive. There are several considerations to upgrading.

1.) I cannot upgrade until EPEL starts releasing items for RHEL 8, and last I looked, they have not done so.

2.) I do not know if I can boot from a thumb drive with my machine. And the RHEL8 release will not fit on a DVD disk. Next time I need to reboot my machine, I will check on this.

3.) Upgrading is a very time consuming proposition. While it takes only a few hours to do the install, fixing up all the little configuration nuisances usually takes me about a month of irritation and swearing. In the meantime, certain applications (gnucash, for one) cannot be used, and this is intolerable as I am treasurer for a non-profit that cannot really tolerate being down for much over a week.

4.) It took me over a month to get VLC to work, and other video display programs could not be made to work, so I must use that. That one is a library hell situation. That is one reason I like Red Hat: they support their releases for 10 years, so I do not normally need to upgrade. I could not stand Fedora because of all the upgrades and short-term support.
