They are trying to capture a core file when a user logs in to their app. They set the max core size to 50M by using ulimit -c. The program calls the setresuid command so it runs as the logged in user. The core file is not being created and they want to know if the setresuid function resets the ulimit -c settings. This is on a RHEL3U4 box. Please let me know if more info is needed.

If you want to increase limits, use /etc/security/limits.conf Thu, 11 Jan 2007 10:03:59 GMT https://community.hpe.com/t5/operating-system-linux/setresuid-behavior/m-p/5022412#M48074 Vitaly Karasik_1 2007-01-11T10:03:59Z https://community.hpe.com/t5/operating-system-linux/setresuid-behavior/m-p/5022413#M48075 the reply I got back helped.
