Backup logfile not being created

[mpinnock]

using log4j with rollingfile appender, however, the system fails to create a backup file after the initial backup file reaches its limit.

This isn't always consistent - for example, sometime I am able to see multiple backup files, but the next time I run the application the first file keeps getting overwritten and a second or subsequent backup files are not created.

Can someone provide assistance with this issue?

Cheers
Michael

More info. Post your logging configuration and information on how your application is put together with respect to logging.

Tim - thanks for your follow-up. I am enclosing a sample of the config file that I am using - it shows the rollingfile appender, file size and number of backup files that I am trying to keep.
