Core dump files (files with the name "core") are created by UNIX processes under certain conditions when processes terminate abnormally. The core dump file will contain process information that might be useful to a programmer or analyst attempting to diagnose a problem. For the rest of us, core dump files are a nuisance, consuming valuable space in our home directories. We will be changing the default system behaviour on CCS administered UNIX systems (eg. mail servers, Phoenix, etc.) to prevent the creation of core dump files and to reduce unneccessary disk usage. If you wish instead, to have core dump files created as before, update your .cshrc file with a line like either of the following: limit coredumpsize unlimited % as before limit coredumpsize 10 % 10K max size for any core dump files Please contact the Help Desk if you have any questions. -- Marshal Linfoot Phone: (416) 736-5257 x22691 Manager, UNIX Technical Support FAX: (416) 736-5701 CCS, York University E-mail: [log in to unmask]
