+++ This bug was initially created as a clone of Bug #1659432 +++ Description of problem: rda_opendir creates and leaks a dict_t xdata_from_req Version-Release number of selected component (if applicable): How reproducible: Consistently. Steps to Reproduce: 1. Create a 1 brick volume and fuse mount it. 2. Create a directory mydir in the volume root. 3. Compile the following test code and run it on the volume in a loop, while checking RES in top output for the fuse mount process. <code> #include <stdio.h> #include <stdlib.h> #include <sys/types.h> #include <dirent.h> int main (int argc, char *argv[]) { DIR *fd = NULL; char *name = NULL; if (argc != 2) { printf ("Usage: %s <dirpath>\n", argv[0]); exit (1); } name = argv[1]; fd = opendir(name); if (!fd) { exit (1); } closedir (fd); } </code> cd /mnt/gluster-mnt Run while (true); do ./a.out ./mydir; done Actual results: Memory use rises constantly. Expected results: Memory usage should stay constant after the initial run.
