Hi All,

Our developers are trying to upload  and activate the PDF's  content through siteadmin , after some time author went to unresponsive state and we are unable to access the server.

Here are my aem details:

Adobe Experience Manager (6.1.0.SP2)

My observations:

-->in error logs i didn't find any error/exception

-->under my /app/temp directory i found apache-tika-7647900487403647892.tmp generating

Can someone please guide me?

Thanks,

Amarnath Polu

Hi ,

Are you using AEM DAM upload functionality?

-->Tried from damadmin as well .but still same issues

what is the CPU and Memory of the Server running AEM?

-->Total VM RAM 7GB, java heap is 5GB allocated

Note: We are trying to upload only 80MB files of pdf and it's not very huge.

Below is stack trace which we found in Heapdump analysis
