Code Corner

Suddenly and without any warning my server stopped recording bandwidth and space usage. After much investigation and without proper support from parallels for one more time I discovered through trial and error that a file in

C:\Program Files\Parallels\Helm4\ScheduledTasks

had been locked (in my case 2.xml) and was partially updated. This meant that the helm application crashed when it was trying to parse an incomplete xml file. This is the definition of bad error handling and poor coding.

Anyway the solution was simple. I deleted the 2.xml file and the control panel became operational again! Not sure if or how I should restore the 2.xml file but for the time being I am happy the thing is running again.

There error message



Helm 4 Application Error.

Unexpected end of file has occurred. The following elements are not closed: translation_variables, result, results, scheduled_task. Line 46, position 30.
