Hi Stephen, Matt,<div>I haven't run rockstar with multiple readers at all. It also doesn't segfault for me, and my scripts successfully continue churning on.</div><div><br></div><div>Also, I've found that in a few places the force resolution is particularly touchy. What I naively thought -- that setting the force resolution to 3x the native resolution would decrease the number of low-mass halos and nail down the high mass ones -- actually created spurious, <i>high</i>-mass halos. I've seen one instance where two large halos are found only ~5kpc from each other, but the second one clearly does not exist, and disappears when the resolution is dropped to from 200pc -> 60pc. I only mention this because we were talking about this off-list, and because in casual testing I noticed this counterintuitive trend. Of course, it could just be that I'm only looking at a few snapshots... but we should definitely keep an option open for manually setting the force resolution.</div>

</div>I think I've found it. What was essentially happening is the<br>
workgroups are supposed to be deleted inside a loop:<br>
<br>
for wg in workgroups:<br>
del wg<br>
<br>
but this doesn't actually delete items from the list, of course.<br>
However, because there was some deletion of things inside wg in that<br>
loop, I think there were references that were left dangling. I'll<br>
issue a PR soon for just that fix.<br>
<br>
Regarding the duplicate halos, I haven't tracked that one down yet.<br>
