Hello,
I am troubleshooting a servlet which is used to upload files. Small
files under 25mb are processed properly. Large files over 50mb are
processed properly. Files with size in the range of 25mb -- 50mb fail
with OutOfMemoryError.
Unfortunately I do not get a Stack Trace. Instead of a Stack Trace I
only get "Java heap space".
I know that the FileUpload component has a threshold with default of
10kb, so that files under 10kb are processed in memory, but files larger
than that are processed using the disk to preserve memory. I do not see
anywhere in the code that the threshold is modified from its default value.
Is there anywhere else in Tomcat that might have a 50mb threshold for IO
operations? Specifically in NioEndpoint since I see this in catalina.out:
Jul 11, 2017 1:23:29 PM org.apache.tomcat.util.net.NioEndpoint$SocketProcessor
doRun
SEVERE:
java.lang.OutOfMemoryError: Java heap space
Running Tomcat 8.0.23 (and yes, I would love to upgrade it but this is
for a large organization and I can not update it at this time).
Am I correct to assume that the error is logged from
https://github.com/apache/tomcat80/blob/TOMCAT_8_0_23/java/org/apache/tomcat/util/net/NioEndpoint.java#L1563
?
Thank you,
