But this is the only function which sets tsd_nalloc, and the original value is 8. Attach to your program with mdb, and do: % mdb -p pid Loading modules: [ ld.so.1 libc.so.1 ] > ::walk ulwps | ::print ulwp_t ul_stsd[] That will print out the thread specific data structures for every thread in the program. See what the tsd_nalloc values are; they should all be powers-of-2 >= 8.
