I have been encountering a problem trying to work with the core dump file. After I decompress the lz4 file and then try to use gdb (gdb /apps/httpd2.5/bin/httpd <core file>), I am getting an error msg in GDG:
Reading symbols from /apps/httpd2.4/bin/httpd...done. "/var/lib/systemd/coredump/core.httpd.1001.9e14cb0299404a82a8df5c73ceab0e83.53762.1739305624000000" is not a core dump: file truncated If I run 'file' on the core file I get: [root@localhost coredump]# file /tmp/core.31929 /tmp/core.31929: ERROR: ELF 64-bit LSB core file, x86-64, version 1 (SYSV) error reading (Invalid argument) Does anyone know what might be causing this? I even worked with one of my colleagues and we tried increasing limits, etc., but to no avail. Thanks!
