It was because of the limit on number of open files (ulimit -n). Currently when perf loads a DSO, it'll look for normal and dynamic symbol tables. And if it fails 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 closing those files even though they're not used. Fix it.
