Issue/Introduction

Description:

In an em.log or similar APM log, what does this mean, in simple terms?

[WARN] [IntroscopeAgent.WilyTransactionStructure]
Transaction trace component limit of 5000 reached, recording of any new components will cease for this transaction.

Solution:

The transaction trace limit is 5000 by default, and it just means that recording of events will be stopped until the limit is increased. It basically refers to trace entries.

A common way to get around this, is to increase the transaction trace limit, to allow for more debugging and other troubleshooting, but such should not be used long-term until the actual cause of excessive tracing has been determined.
