hi shwetha, do you have the nfs logs corresponding to this valgrind report? when the process is terminated, there could still be pending replies, hence the missing unref/free's on inodes and fd's, which happen in cbk's. CHANGE: http://review.gluster.com/2994 (core: fix all the iobuf related refs and unrefs) merged in master by Vijay Bellur (vijay) |
