The check has a default time limit of 60 seconds. If the Agent is unable to check the size of all monitored files within this time limit, then the Agent will return a timeout error. This error will include the size of all of the files it was able to check. Should you wish to change the default time limit for the check please perform the following steps:
Navigate to the Agent installation folder. By default: C:\Program Files\Advanced Monitoring Agent
Open the settings.ini file
Enter the following in the [TEST_FILESIZE] section:
MAX_EXEC_TIME=XXXXX replacing XXXXX with the new timeout period in milliseconds.
This will increase the timeout period for the File Size Check to 90 seconds.
The Agent console must be closed for any changes made in the settings.ini file to take effect
