Hello HomerJ,

This error can be triggered with larger files. Some performance fuses were inserted into QC's code in order to alert you when performing ''heavy'' actions that might impact the entire server. The recommendation in cases of hitting the fuse is to try and break down those actions into smaller steps.

If splitting your test set is not an option, in order to avoid hitting the fuse, you can override its fuse size limit for the system. You can accomplish this with the following steps:
* Login to Site Admin
* Go to ''Site Configuration'' tab
* Add a new parameter
o Parameter: CLOSURE_FACT_BETWEEN_DEPTH_FACTOR_PCT
o Value: 500
* Restart the server

If this doesn't help, you can do accomplish the same with the addition of the following parameter:
Parameter name = CLOSURE_ROWS_FUSE_FACTOR_PCT
you should start with the value first set at 500
if the first parameter doesn't work, adding the second parameter should hopefully work , if neither works, increase the value.

Clearly, this change is reversible, so it is suggested validating its effect on the overall performance of QC and in case that overload is noticeable, consider removing the above added parameters and split the copy of your test-set to not exceed the filter size.

Hope this helps,
Dan
