How to detect repeating log entries?

[greathera]

Hello,
When my application fails it will generate repeating log lines. I must detect where there are repeating log entries to determine what thread is causing the problem. Each time there is a failure the content of the repeating logs will be different depending on the thread / process that is having the problem. Can Splunk detect a sequence of repeating log entries? How would I do this? I see there is a md5 function and wonder if this can used to generate a hash per log line and then compare each new log entry to the one before it (or the log entry two lines back?).
Thank you for any help on this.

Hello

You could use the cluster command:

http://docs.splunk.com/Documentation/Splunk/6.0/SearchReference/Cluster

That groups similar events.
