huge number of api call "sr.getAllUnhealthyVdiChainsLength"  in tasks
- 
 
- 
 Same problem here 300+ sessions and counting 
  
 XAPI restart did not solve the issue...
- 
 Doesn't seem to be respecting [NOBAK] anymore for storage repos. Tried '[NOSNAP][NOBAK] StorageName' and it still grabs it. 
- 
 On the VDI name, right? 
- 
 @olivierlambert I believe so. It is the Disks tab of a VM. [NOBAK] was working but now the NAS is complaining about storage space. This VM has a disk on the NAS so it is backing it up twice. Added [NOSNAP] just as a test with the same result. 
  It is running a full backup if that makes any difference. 
- 
 Ping @julien-f 
- 
 @ryan-gravel I cannot reproduce, both Full Backup and Incremental Backup correctly ignore VDIs with [NOBAK]in their name label.
- 
 @julien-f It's happening to me too... my [NOBAK]disk is being backed up now (commit 0e4a3) using the normal Backup (running a full).

 With today's update (feat: release 5.96.0, master 96b7673) things are working well again. I have not seen any Orphan VDI/snapshots or stuck Control Domain VDIs (but it may take time to test). Thanks to the Vates team!

 Hello, can you please try the buffered-task-eventsbranch and let me know if that solves the issue?
