I've not really tested an app like that, but I would expect that freeing the memory should prevent your virtual space from growing. I would recheck your code and maybe add some tracing to make sure that everything really does get freed -- or try the libibverbs valgrind support ;) If you send me your code I may be able to find some time to investigate too. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
