These WU's are using about 1GB each on my machine (16 threads 12gb ram) more than 4 causes it to lockup.
I'm looking to limit concurrent running WU's to 4.
I have created an app.comfig.xml file in the program date dir with

<app_config>
<project_max_concurrent>4</project_max_concurrent>
<report_results_immediately>0</report_results_immediately>
</app_config>

This works great for SPT@Home but does nothing for NFS@Home. Not overly familiar with creating these files here,

THANKS

I recommend running both 16e Lattice Sieve (small lasievef_small and lasieve5f/V5) as a mean to manage your memory requirements. The small will use less than 1GB of memory.

You can also go to the boinc client settings and force it to only use X % of the CPU cores.

Thanks gives me some direction to go
