Hello Guys, One simple shell fork bomb was breaking all the cluster (11 virtual machines). This not solve: http://www.cyberciti.biz/tips/linux-limiting-user-process.html (If I run as root, the virtual machine goes down, the I/O on GFS stop and the cluster does not fence the virtual machine automatic). The I/O return only if I fence_node manually. PS: IF the fork bomb as write in C, does not break the cluster. Only the Shell one... [root@cluster-11 ~]# ulimit -a | grep proc max user processes (-u) 512 [root@cluster-11 ~]# cat fork.c #include <unistd.h> int main(int argc, char* argv[]) { while(1) fork(); return 0; } Fork Shell: # :(){ :|:& };: Thanks a lot! -- Tiago Cruz http://everlinux.com Linux User #282636 -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
