To help you better, I need a bit more detail, but here’s a general checklist to troubleshoot a crashing server: Official Website!
Basic Troubleshooting Checklist
Check Logs
System logs: /var/log/syslog
, /var/log/messages
, or event viewer
on Windows.
Application logs: Depends on the server (e.g., Apache, Nginx, Node.js).
Look for errors, crashes, or "out of memory" messages.
Resource Usage
Monitor CPU, RAM, disk, and I/O usage with:
Linux: top
, htop
, vmstat
, iostat
Windows: Task Manager or Resource Monitor
Crashes due to memory leaks or overload are common.
Disk Space
Ensure there’s enough free space on the root and log partitions.
Linux: df -h
Windows: Check drive properties
Services or Dependencies Failing
Check if a dependent service (like a database) is crashing first.
Confirm services restart properly.
Recent Changes
Did you recently deploy code, apply updates, or change configuration?
Security Breaches
Check for unauthorized access or malware.
Audit logs for suspicious activity.
Hardware Issues
For physical servers, check for hardware faults.
For cloud servers, check provider's health dashboards.
If you can provide:
Server OS
What software is running
Logs or error messages
When crashes happen (random or under load)
…I can give you much more specific help.
