Sort type TREE not defined in (TCU50) tab_z30_sort; slow response time

Description:
We periodically have very slow response time.

I noticed a lot of entries in the pc_server log like the one below that begin with an error message about "build_z30_sort_key: Sort type TREE not defined in (xxx50) tab_z30_sort" -- followed by 799 "c1506_reply" messages.

Could the sort key error be causing a response time problem?

Resolution:
The error message occurs because the operator has asked for a sort of the items in the tree (the lower left-hand pane) and the xxx50 tab_z30_sort table has no entries with the table "TREE" in column 1.

The items will display despite the lack of this TREE sort. The lack of such an entry can not be the cause of the slow response time.
