1. Slice mailing list isn't working: The problem was due to a bug in the aliasing script. It is fixed, and in case of a future problem, take a look at /usr/bin/gen_aliases.py on golf. Reid also mentions this below.
2. pl_mom kills a slice: When we get an apology email from the users, it often proves useful to provide the CoMon's memory consumption page for the slice as reference to help them debug the problem. At least they will stop their experiment on the most problematic nodes.
The CoMon URL is http://comon.cs.princeton.edu/status/tabulator.cgi?table=slices/table_{slice}&sort=6
where you need to replace {slice} with the actual slice name.
3. NodeManager gets stuck at boot[#21930]: I believe Faiyaz is working on this problem, but in the mean time, 1) reboot the node 2) if rebooting doesn't work, reinstall it.
4. Query about DevBox[#21958]: DevBox is discontinued. Recommend them to use myplc.
