# 10.4.4.2.2 Analysis Plug-in – Queue Properties

The CRC has an optional plug-in called Analysis plug-ins. This plug-in has its own set of properties defined in the crc.properties file. These properties define how long a job will run in each queue (medium or large) before it times out and moves onto the next queue.

1. In the **crc.properties** file scroll to the section called **Analysis Queue properties**.

2. Edit the length of time a process should run before timing out.

  **Analysis Queue properties**

edu.harvard.i2b2.crc.analysis.queue.medium.timeoutmills=3000

edu.harvard.i2b2.crc.analysis.queue.medium.maxjobcount=4

edu.harvard.i2b2.crc.analysis.queue.large.timeoutmills=43200000

edu.harvard.i2b2.crc.analysis.queue.large.maxjobcount=1

edu.harvard.i2b2.crc.analysis.queue.medium.jobcheck.timemills=60000

edu.harvard.i2b2.crc.analysis.queue.large.jobcheck.timemills=60000

3. Save your changes and close the file.
