2024-12-03 15:10:55 | WARN [qtp788316339-2235] (ServletHandler.java:540) - Error for /searchDIM
java.lang.OutOfMemoryError: Java heap space

this always happen when recieving CT scan images ( many images )

but when using htop to monitor, server still got headrooms
( 4Gb use out of 8gb RAM and 400mb of 2GB swap use )

i notice this will happened when approacing 3GB memory usage for dicoogle..

is this the classic 32bit OOM?

[beavermml]

using openJDK 11 64bit..

and Dicoogle spike the CPU 100% at that time.. i need to manually restart the process..

An error on /searchDIM suggests that the problem is with the querying rather than the indexing. It may help us understand the situation if you provide the following details:

• How many studies/series were sent to the archive?
• How many DICOM files were there in total?
• How large in bytes is each file on average?
• What is the SOP class UID?
• What is the Transfer Syntax UID?
• Were any extra JVM properties set? Have you tried setting -Xmx manually? (e.g. -Xmx4G)

/searchDIM is because my user is searching result and the server hang ( no result ).. so the log is just coincident to be there

the ctscan sending 1600 images in total
400kbs avg per file

now im trying to set -Xmx4g in the DicoogleServer.sh file to test
