Last night suddenly got an error "System Exception(s) Error 1: Attempted to read or write protected memory. This is often an indication that other memory is corrupt" when was uploading excel report to asp.net application.
No updates or software installed on this server. i disabled firewall and Antivirus and checked but no luck.
Asp.net application is on windows 2008 R2 server, IIS7.0, framework 4.0 and DB is SQL 2008 R2 standard server.
Can anyone tell me what is the issue exactly?
