-----------------------------------------
Summary: FileConsumer OutOfMemory for big files in Unix
Key: CAMEL-20556
URL: https://issues.apache.org/jira/browse/CAMEL-20556
Project: Camel
Issue Type: Bug
Components: camel-file
Affects Versions: 3.20.9, 3.20.3
Reporter: Alexander Anpilov
For clarity, I have tested and described issue with simple routes:
1. *FileConsumer*
**
{code:java}
from("file:/path")
.log("Received file: ${file:name}"); {code}
2. *File pollEnrich*
{code:java}
from("direct:start")
.setProperty("SOURCE_URI", simple("{{path_to_folder}}"))
.pollEnrich().exchangeProperty("SOURCE_URI").timeout(60000)
.log("Received file: ${file:name}"); {code}
My process receive big files (more than 4x of Java XMX) and running as
spring-boot app on Kubernetes.
After upgrading from camel-3.20.2 to camel-3.20.9, the OutOfMemory error occurs
on consume. I have rolled back and checked with camel-3.20.2 again on the same
files - everything OK.
It seems, that FileConsumer publish file content into memory, instead of using
streams.
The problem starts from version camel-3.20.3 and reproduced up to 3.20.9.
*BUT:* I couldn't reproduce problem on Windows, only in Unix env.
