I'm talking about this host in particular.... host

It works well for a day or so, and then fails every WU with this message:

<core_client_version>7.6.33</core_client_version>
<![CDATA[
<message>
too many exit(0)s
</message>
]]>


Any help would be appreciated!
Thank you

You have 2806.71 MB of memory. That is probably not enough. The recommended amount is 1 GB per core.
How many cores are you running?

Some tasks take a lot more, as you know.

The new ones may use less memory, but maybe they have issued some that are like the older ones.

Hi Chilean

I have an i3 that's the same generation and found that running three threads was as efficient as running four. I think the cache is probably the reason for that- each task gets access to more of the cache if there are fewer threads competing for it, but it will also mean there's more RAM available for each thread. Also, the first two tasks get a full core each, whereas the next two only get a virtual CPU each (so they'll slow down the first two threads by competing for resources), so I'd suggest running two or three threads on that machine, by reducing the "Usage Limits" to 50% or 75% of the CPUs.

Also, under "Disk and memory", is "Leave non-GPU tasks in memory while suspended" checked? I also bump the "When computer is not in use, use at most" up to 95%.
