[infinispan-issues] [JBoss JIRA] (ISPN-8166) Writes via memcached server cause UnknownOperationException

Tristan Tarrant created ISPN-8166: ------------------------------------- Summary: Writes via memcached server cause UnknownOperationException Key: ISPN-8166 URL: https://issues.jboss.org/browse/ISPN-8166 Project: Infinispan Issue Type: Bug Components: Server Affects Versions: 8.2.6.Final, 9.0.1.Final, 9.1.0.Final Environment: Ubuntu 16.04.1 LTS openjdk version "1.8.0_91" OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14) OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode) The bug can be reproduced with OS X and other Linux distributions as well Reporter: Wolfram Huesken Assignee: Tristan Tarrant Fix For: 9.0.4.Final, 9.1.1.Final, 8.2.9.Final We're using the stable server version (http://infinispan.org/download/) as a memcached replacement in a PHP application. When we're writing keys (or values) with different sizes via memcached, we encounter the following exception: {{17:14:42,531 ERROR [org.infinispan.server.memcached.RequestResolver$] (MemcachedServerWorker-8-1) ISPN005003: Exception reported: org.infinispan.server.memcached.UnknownOperationException: Unknown operation: }} When the exception occurs, the data is not stored. We're currently closing and reopening the connection after an error like that occurred, but it's slowing down the data transfer quite a lot. The bug is not only related to the server, but happens with the embedded version of infinispan, too. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
