Memcache service stopped

Original Question or Issue:

Memcache service appears to have stopped last night, triggering the Admin warning “Memcache Server Not Running” and repeated log errors.

---

Environment:

• Product - FileCloud Server
• Version - 23.242
• Platform - Any

---

Steps to Reproduce:

• FileCloud upgrade to v23.242.x (or later)
• Memcache service on the configured host stops
• Admin UI displays “Memcache Server Not Running”
• FileCloud server logs fill with memcache-related errors

---

Error or Log Message:

ERROR: Failed to set any Memcached connection

---

Defect or Enhancement Number:

 

---

Cause:

Legacy configuration was still pointing at a remote IP address via the old TONIDOCLOUD_MEMCACHED_SERVER settings, but that memcached instance was down/unreachable.

---

Resolution or Workaround:

Switched to the new HA-aware single-node format and pointed at the local daemon:

• Edit /var/www/html/config/cloudconfig.php

--// Comment out or remove the old lines:

// define("TONIDOCLOUD_MEMCACHED_SERVER", "<server_ip>");

// define("TONIDOCLOUD_MEMCACHED_PORT", <server_port>);

--// Add the new setting:

define("TONIDOCLOUD_MEMCACHED_SERVERS", "<host_ip>:<port>");

• Restart or reload Apache to pick up the change:

sudo systemctl restart apache2

or

sudo systemctl reload httpd

Once applied, the Admin warning cleared and the “Failed to set any Memcached connection” errors stopped.
