Reports Plugin failing with errors (4032594)

When running Reports in NetVault (version 9.x or 10.x), an error is thrown

9.x Error:  A Plugin Died Unexpectedly

10.x Error: Provider "Reports" Failed when generating report

Cause 1

This error indicates that the jobhistory.bin has gotten corrupted - most likely in the upgrade process.

The jobhistory.bin file is a file that contains the list of the recently ran, unpurged reports.

Observing the debug from the Reports Plugin, we see this type of error below:

FILE 50764 526 0 81625 FileDelete failed to delete file 'D:\Program Files (x86)\Quest Software\NetVault Backup\reports\produced\20130628\records\restoresummary%20130628182646%001%jobhistory'

REPPPRGE 50764 12 0 81625 PurgeOldJobComponents(): failed to delete D:\Program Files (x86)\Quest Software\NetVault Backup\reports\produced\20

Resolution 1 (For Cause 1)

The proposed resolution to this error is to delete 'jobhistory.bin' in the folder"/reports"

Steps to remove properly:

1. Stop the NV Service on the NetVault Server
2. Go to the NV_Home/Reports directory
3. Delete the 'jobhistory.bin' file
4. Start the NV Service back up
5. A new 'jobhistory.bin' file will be created                                                                                                                                                                Now, you should be able to go into Reports and successfully generate a report.

Resolution 2 (For Cause 2)

Install a fresh copy of netvault Backup version 10 or netvault Backup version 11
