Suggestions for increasing the available memory
If the amount of memory used is over 95 percent, or if you receive out-of-memory errors, you should
reduce the amount of memory that is used.
Some suggestions for increasing the available memory:
•
Turn the instrument off and on. This deletes scripts that have not been saved and reloads only
scripts that have been stored in nonvolatile memory.
•
Consider removing unused reading buffers.
•
Consider resizing reading buffers to a smaller size.
•
Reduce the number of TSP-Link
®
nodes.
•
Delete unneeded global variables from the run-time environment by setting them to
nil
.
•
Adjust the
collectgarbage()
settings in Lua. See
(on page 7-26)
for more information.
•
Review scripts to improve their memory usage. In particular, you can see memory gains by
changing string concatenation lines into a Lua table of string entries. You can then use the
table.concat()
function to create the final string concatenation.
