I get this error on all my downloaded workunits from my own Boinc server which is running the "Uppercase" application:

The correct results are uploaded to /upload but the database "results" table says they failed with exit code: -177 (0xffffffffffffff4f) ERR_RSC_LIMIT_EXCEEDED.

Keep in my this is a trivial application which only reads in text and converts it to all upper case. So, I am a bit confused as to how my CPU can be "too slow" to run it.

Server is running on RedHat 9 and client is running on Vista.

On an OpenSuse client I get this sort error (but the correct result is uploaded):

Thanks and help, as always, is appreciated.

You should increase the <rsc_fpops_bound> value on your workunit template. See Workunit details.
