Created attachment 608183 [details] clustat core file Description of problem: I have correctly running cluster. I change cluster.conf on one of the nodes with non-valid xml. I run ccs_tool to update this config version to all the nodes which it correctly does. Running "clustat" after that on any of the nodes leads to Segmentation Fault. Version-Release number of selected component (if applicable): This is RHEL5.9-candidate-20120813, rgmanager-2.0.52-34, running on ia64. How reproducible: Always. Steps to Reproduce: 1. Have three node cluster on rhel5.9 ia64. 2. Modify /etc/cluster/cluster.conf on any of the nodes as follows (add <a> tag and increase config_version): <?xml version="1.0"?> <a> <cluster name="a_cluster" config_version="303"> ... </cluster> </a> 3. run: ccs_tool update /etc/cluster/cluster.conf 4. check that all nodes report that the config has been updated correctly. 5. run: clustat Actual results: Segmentation Fault (core dumped) Expected results: Cluster status shown. Additional info: Info from the core attached: Core was generated by `clustat'. Program terminated with signal 11, Segmentation fault. #0 0x2000000000259890 in strcmp () from /lib/libc.so.6.1 (gdb) bt full #0 0x2000000000259890 in strcmp () from /lib/libc.so.6.1 No symbol table info available. #1 0x4000000000007b40 in add_missing (all=0x600000000000d9f0, these=0x600000000000d600) at clustat.c:396 x = 0 y = 0 addflag = 0 m = 0x0 nn = 0x0 #2 0x400000000000c350 in build_member_list (ch=0x600000000000c010, lid=0x60000fffffd6b758) at clustat.c:983 all = 0x600000000000d9f0 part = 0x600000000000d600 m = 0x0 root = 1 x = 0 #3 0x400000000000d190 in main (argc=1, argv=0x60000fffffd6ba88) at clustat.c:1173 qs = 1 ret = 0 membership = 0x200000000004f378 rgs = 0x0 local_node_id = -2705464 fast = 0 runtype = 0 now = 2305843009215291960 ch = 0x600000000000c010 ci = {ci_name = "a_cluster\000\000\000\000\000\000\000", ci_number = 50356, ci_generation = 512} refresh_sec = 0 errors = 0 opt = -1 xml = 0 flags = 0 member_name = 0x0 rg_name = 0x0 real_rg_name = "\000\000\000\000\340\343\004\000\000\000\000 @\267\326\377\377\017\000`", '\000' <repeats 40 times>, "8b\030" (gdb) info threads * 1 Thread 0x20000000000ada60 (LWP 31939) 0x2000000000259890 in strcmp () from /lib/libc.so.6.1
