# 2765 Dead Sessions that Contain Sensitive Query Result Sets that Reference Functions Can Cause AV

---

When I connect as a single user to the EDB server, do a few not really sophisticated things (opening a few tables, traversing some data to stringlists, display data in grids and treeviews, I think the DB trees are setting a big amount of bookmarks) and then close the application, the line in the EDB server grid showing the connection disappears instantly, and everything is fine.

When I do the same thing, but encounter an exception, after that halt program execution and terminate the program with STRG+F2, the line in the EDB server grid is still present. The adress column shows "Adress (disconnected)". Now I wait 5 minutes. After that, exactly at the moment this line disappears, the CPU load goes up to 100% and remains so until the server task is killed.

More information:

When you open a query or a table in EDB Manager with an external function in the where-clause or the filter expression, and kill the EDB Manager task after that, you see this error. With a SQL/PSM function it works.
