Overview

You find that Bonzai content is slow to load (takes >2 minutes), and there are errors seen in Chrome's Network Activity and front-end server event logs.

• The web front-end server event logs show event 2138 repeatedly occurring
  • The SharePoint Health Analyzer detected a condition requiring your attention.  Drives are at risk of running out of free space.
  • Available drive space is less than five times the value of physical memory. This is dangerous because it does not provide enough room for a full memory dump with continued operation.
  • There were also blob cache errors found
• The Chrome Network Activity is in the below screenshot and primarily have these errors:
  • “BONZAI ERROR: The operation has timed out.”
  • “The operation has timed out."

The HAR file also finds these errors:

"SchemaVersion":"15.0.0.0",
"LibraryVersion":"16.0.4546.1000",
"ErrorInfo":{

"ErrorValue":null,"TraceCorrelationId":"6731ac9f-7ca7-6037-b46b-462748fe3071",

Solution

1. Please see the article Request timed out to adjust the timeout values and allow additional time for content to load.
2. To resolve the 2138 error, please ensure there is 5 times (than the memory) the space free on the C drive. Eg: If you have 16 GB memory, then there should be at least 80 GB free space.
3. Ensure that cdn.bonzaicloud.com is allowed in firewalls as the issue could be occurring when connecting to one of our CDN servers outside of North America during times of high bandwidth to our CDN servers.
4. To resolve the blob cache error, flush the blob cache using Flush the BLOB cache in SharePoint Server.

Testing

Check to see if content loading time is back to normal. 

If this does not resolve the issue, please contact Bonzai Support and send the HAR file by following the steps in the article Generating a HAR file for troubleshooting.
