1) Message boards : Number crunching : Must set rsc_memory_bound correctly (Message 2137)

It looks like this change is being reverted for now, per David's email below.
So, there is no longer an immediate need to correct the value...
But please consider setting it correctly at some point, in case it gets used by the client in the future.

WUProp Team:

You need to change your work unit parameters, to properly set <rsc_memory_bound> correctly. BOINC 7.3.14 alpha (and potentially future versions also) will read that value, and compare it to the Working Set size, and will auto-abort the work unit if it exceeds the bound.

As of right now, I am getting errors due to your incorrect settings.

For example:
Exit status 198 (0xc6) EXIT_MEM_LIMIT_EXCEEDED
working set size > workunit.rsc_memory_bound: 97.10MB > 95.37MB

Could you please promptly fix this?
