Environment

ConnectALL 2.11

Cause

This is caused by a corrupt file in the ConnectALL temporary directory

Resolution

1. Stop your mulesoft service
2. Navigate to your mulesoft home directory
3. Go into the mule-standalone-3.9.0/.mule directory
4. Delete the ConnectALL temporary directory that corresponds with the version you are running.  For example if you are running 2.11, your directory name will be ConnectAll-2.11.2.5.Ra487d55a203c4d830c4c0dff656501fa3ac12396
5. Restart your mulesoft service
