According to the wiki, table incr takes two options beyond the subtable name: the key and the delta. So in the above statement, the "AccumulatedResponseTime" string would be the key - an arbitrary string value, and $currentResponseTime would be the delta - or amount to increment by. Without the delta the (numeric) table entry would be incremented by 1. If the table entry didn't exist, the key would be created with a value of 0. Is it possible then that $currentResponseTime is not a number?

 

You could, at the very least, encapsulate all of this in a catch statement:

Or verify that the delta value is a number before using it.
