Out of Memory – HTML to PDF

#27081

We have a web application using pd4ml running on:

java 6
weblogic server 10.3
pd4ml 370fx2

We had occasionally Out Of Memory error with thread stucked on:

which is more than the configured time (StuckThreadMaxTime) of “600” seconds. Stack trace:

java.util.zip.Deflater.init(Native Method)

java.util.zip.Deflater.(Deflater.java:135)

java.util.zip.Deflater.(Deflater.java:144)

Is it possible that newer version of library solved this problem ?

One year ago it was a report of a similar issue on
JRE 1.7.0u67
CentOS 6.6 x64

The error had also been thrown by java.util.zip.Deflater. It is a very standard Java class and we did not touch the corresponding code probably since versions 2.x of PD4ML and never had troubles with it before.

Last time we suspected a JDK installation inconsistencies (or may be even a palform-specific bug), occasionally hit by v3.6.1b1. A JDK re-install and a switching to v3.9.5 have solved the issue that time. But we did not determine what exactly was “the cure”. I would recommend to switch to PD4ML v398fx5; and if it does not help, to re-install the JDK.
