Task which is created by vsphere SDK can be suspended forever

Dear all

I have a perl script, which use vSphere SDK for Perl to create a task (Please refer to https://www.vmware.com/support/developer/converter-sdk/conv60_apireference/vim.TaskManager.html#createTask), update task progress and set task status. The script and vCenter Server are in different machines. After I create a task, the connection between the two machines are lost, so I cannot set status of task to be completed, and the task will be suspend forever on vCenter Server. Is there any way to resolve that problem?

Thanks and best regards
