Error description
While running IBM Rational ClearCase version 8.0.1.9 a view_server segmentation fault can occur, if the eacl cache gets flushed between retransmissions of an RPC from a client. The second transmission triggers view_server to refer to memory that has been reused causing it to terminate. An example backtrace of the core file (from a Solaris 11 host): Program terminated with signal 11, Segmentation fault. #0 0xfe4bc183 in xdr_tbs_acl_cooked_info_block () from /opt/rational/clearcase/shlib/libatriatbs.so (gdb) #0 0xfe4bc183 in xdr_tbs_acl_cooked_info_block () from /opt/rational/clearcase/shlib/libatriatbs.so #1 0xfe4bc6ba in xdr_tbs_sid_acl_fragment_t () from /opt/rational/clearcase/shlib/libatriatbs.so #2 0x080c7b61 in xdr_view_eacl_rolemap_reply_t () #3 0xfe42510f in xdr_ks_accepted_reply () from /opt/rational/clearcase/shlib/libatriaks.so #4 0xf3c3659b in xdr_union () from /usr/lib/libnsl.so.1 #5 0xfe4251ff in xdr_ks_replymsg () from /opt/rational/clearcase/shlib/libatriaks.so #6 0xfe435f56 in ks_svc_dg_reply () from /opt/rational/clearcase/shlib/libatriaks.so #7 0xfe434878 in ks_svc_sendreply () from /opt/rational/clearcase/shlib/libatriaks.so #8 0x080b0fed in view_server_disp () #9 0xfe434e3f in ks_svc_process_request () from /opt/rational/clearcase/shlib/libatriaks.so #10 0xfe434cad in ks_svc_getreqset () from /opt/rational/clearcase/shlib/libatriaks.so #11 0x080b2e50 in client_rpc () #12 0xfe42974d in rt_wait () from /opt/rational/clearcase/shlib/libatriaks.so #13 0xfe429f9c in rt_run () from /opt/rational/clearcase/shlib/libatriaks.so #14 0x080922b4 in main () WORKAROUND: None.
