Stephane reported that perf report and annotate failed to process data using lots of (> 500) shared libraries. It was because of the limit on number of open files (ulimit -n).
Currently when perf loads dso, it'll look for normal and dynamic symbol tables. And if it failed to find out both tables, it'll iterate all of possible symtab types. But many of them are useless since they have no additional information and the problem is that it's not close those files even though they're not used. Fix it.
