Hm. Duncan was right -- I was thinking of scoring so this isn't it. > Btw, I verified running my same distro but 32bit version (same > packages), and no problems at all. Maybe 64bit issue..? Triggered by > something else in the system (because it ran fine until few months back) Seems to me I've read several times that 64-bit gcc and friends are not really ready for prime time yet, but that's hearsay, not experience.

Yes, what you are doing here is taking random samples and looking for places in the code that appear in every sample. For example your backtraces all include calls to MyTree::add_articles. This depends on statistics, and you know how *they* behave. I personally would start with strace because it will print every system call, not just random ones. Have you used strace before? It's pretty simple to run, not so easy to interpret the output sometimes. Example: use 'top' to find the process that's using up the cpu, and then start strace like this: #strace -p pid-of-greedy-process and be prepared for tons of output to the console (or you can send it to a file instead with the -o flag). Because pan is stuck in a loop somewhere, you should have plenty of data in two seconds or so, then hit Ctrl-C to stop strace. Then the trick is to find a repeating pattern near the end of the strace output where you see the same system calls over and over again, and that should point you to what pan is doing with all those cpu cycles.
