Aidan McGurn created TS-1457:
--------------------------------
Summary: transforms during video requests cause massive memory
growth
Key: TS-1457
URL: https://issues.apache.org/jira/browse/TS-1457
Project: Traffic Server
Issue Type: Bug
Components: Core
Affects Versions: 3.2.0
Environment: Linux RHEL6.2
Reporter: Aidan McGurn
Priority: Critical
Running the null-transform example object over 3.2.0, shows massive memory
growth -
This could be seen on our system since using 3.2.0 with custom plugin which
invokes transforms - under load ~6K and with video content (only Video - small
files are ok), a huge growth was seen (GB's) such that it crashes the load test
machine.
heap profiles are attached for comparison:
-null transform example so over 3.2.0
-NO null transform over 3.2.0
-null transform example so over 3.0.2
As can be seen no issue in 3.0.2 -
The profiles show clearly the call chain is different for both releases
