Hi, a newbie here !
I have had several errors like this.
My question is:
  • Is this a problem with my system or the work unit ?
    What, if any, action should I take ?

This appears to be a problem with the WU, possibly connected with the number of CPU threads being used in this case - 16. Usually you would not need to take any action, after a few retries the client should return the WU including the errors logged for the researcher to check on. On Linux systems there is a bug where some errors are treated as minor, and the client may loop instead of moving on to another WU. If that happens we can give directions for how to clear that up.

In the case it appears the WU was returned by you, it can be looked up in the stats database here - https://apps.foldingathome.org/wu#proje ... 102&gen=28.
