Cisco issues alert for defective memory sticks in its servers

Cisco is urging customers to replace flawed memory sticks in some of its Unified Computing System (UCS) servers before they fail.

The problem is caused by a manufacturing error in 24 dual in-line memory modules (DIMM) that exhibit persistent correctable memory errors that if left in place could knock the servers offline. The problem is found in 16GB, 32GB, and 64GB memory DIMMs.
