Investigation of DBLE "no handler" Log Entries and MySQL Connection‑Timeout Error Handling

This article investigates why DBLE repeatedly logs "no handler" messages by analyzing DBLE and MySQL logs, using Arthas to trace the call chain, reproducing the scenario with timeout settings, capturing network traffic, and explaining the MySQL 8.0.24 error‑packet behavior that leads to the observed logs.

Root Cause Analysis and Resolution of Intermittent Redis Connection Failures

This article presents a detailed investigation of occasional Redis connection errors in a large‑scale production environment, analyzing network packets, TCP backlog behavior, Redis internal client‑cron logic, jemalloc memory reclamation, and ultimately resolving the issue by adjusting query‑buffer handling and upgrading Redis to a newer version.

Investigating Intermittent Memcache set/add Failures in PHP Memcache Extension 2.2.7

The intermittent set/add failures observed with PHP’s Memcache extension 2.2.7 are caused by its built‑in 15‑second retry interval (MMC_DEFAULT_RETRY = 15) that marks the connection permanently failed after a poll timeout, and can be resolved by specifying the hidden fourth ‘timeoutms’ parameter, adjusting php.ini, or migrating to the newer Memcached extension.

Why Short TCP Connections Fail: Decoding Errors 110 & 99 and Fixes

When clients frequently use short TCP connections they often encounter error 110 (connection timeout) and error 99 (cannot assign requested address), which stem from TIME‑WAIT port exhaustion and server listen‑queue overflow, and this article explains the causes and practical solutions.

In‑Depth Analysis of TCP Connection Timeout, TIME_WAIT, Nagle Algorithm and Kernel Parameters

This article examines three common TCP issues—missing client‑side socket timeouts leading to monitor‑killed processes, excessive TIME_WAIT sockets after service failures and their kernel tunables, and 40 ms keep‑alive latency caused by Nagle and delayed ACK—explaining kernel behavior and offering practical configuration fixes.
