I have a custom list in my SharePoint site and there is a webpart which inserts items to that list. This implementation was working fine until recently, when we observed that there are duplicate items getting generated.
Precisely, I observed that webpart is inserting only 1 item. however, 1 more identical item getting generated after brief interval of ~5 minutes.
Following are few more details to identify the cause :
item count 172000
Users in site : ~2000
Content DB size : 200 GB
4: Environment : SP 2013 on Prem.
Thanks
