Hi,
Got the error below:
Exception in thread "Thread-35": java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOf(Arrays.java:3236)
at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:118)
at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93)
at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:153)
at com.ib.client.EMessage.<init>(EMessage.java:18)

at com.ib.client.EReader.putMessageToQueue(EReader.java:83)
at com.ib.client.EReader.run(EReader.java:61)
Tried using the java heap clean I found on this forum (see below) but didnt' help. Any other tips please? Thanks.
function [] = jheapcl(verbose)
if nargin < 1
verbose = 0;
end
org.dt.matlab.utilities.JavaMemoryCleaner.clear(verbose)

请先登录，再回答此问题。

Hello Azura,
Usually the problem can happen if Java Heap Memory set for MATLAB is too low. Please try increasing the java heap space following the Article mentioned below or start MATLAB in -nojvm mode.
Heap space: https://www.mathworks.com/help/matlab/matlab_external/java-heap-memory-preferences.html
-nojvm mode: https://www.mathworks.com/help/matlab/matlab_env/commonly-used-startup-options.html
