Microsoft warns MSMQ may fail after update, breaking apps

Abstract

Another person posted a query on a different Microsoft forum about a building in an unnamed city being without its fire alarm or smoke detector systems. Symptoms include: MSMQ becoming inactive; Internet Information Services (IIS) sites failing with “Insufficient resources to perform operation” errors; applications unable to write to queues; errors such as “The message file ‘C:\Windows\System32\msmq\storage*.mq’ cannot be created” when creating message files; misleading log entries such as “There is insufficient disk space or memory”, despite sufficient disk space and memory being available. [...]attempts to send messages via MSMQ APIs might fail with resource errors.
