I'm trying to troubleshoot a memory issue on one of my servers. Some time ago a daemon my company is developing crashed with segmentation errors. All would be somewhat fine, but seconds later other services (Nginx, postgress, syslog, ssh) also started crashing, also with segmentation errors. This looks to me like either environmental/HW issue or kernel/system library bug. Is there something I can do besides a long term memtest or migrating to another system?
