You mentioned somewhere that the images for the programs which failed are located on NFS volume ? What is in dmesg ? I believe that pager somehow fails to page in, and this causes both access errors in the live processes (SIGSEGV) and EFAULT when kernel reads process mappings to dump them into core files. --=20 You are receiving this mail because: You are the assignee for the bug.=
