As it'll likely be a while before I migrate PIDA to MySQL, I wanted to pass along the following tip for those of you who are  hitting the virtual memory consumption limitation when loading larged PIDA databases.

During the pida_dump analysis, select "bb" (basic blocks) instead of "full" analysis. Stalking does not require per-instruction information and there is a drastic reduction in memory usage when falling back from full to bb only. If you are stalking something even larger and are only interested in hit functions, you can further scale back to function only analysis.

As I get more questions from people I will add more tips under this specific topic.

So, along those lines, I've got a list of Paimei bugs and suggestions.  Have you got a Bugzilla or equivalent going somewhere for it?  Are patches just being email to you for now?  Do you prefer to use OpenRCE for discussions?

For example, I found out the hard way last night that the pida file and process name are case sensitive.  If your pida file refers to isuck.exe, but the process actually runs as iSuck.exe, you will just fail to get any hits.

I keep a bug list. Please e-mail me with whatever bugs you find. If you have a generic question that might benefit others, feel free to use the forums.
