If ManagedOfficeProcess.doTerminateProcess fails jodconverter stays in nonoperable state

[Zhivko]

There is no error in logs if "ManagedOfficeProcess.doTerminateProcess"
fails to execute. If this happens jodconverter stays in nonoperable
state (Ubuntu 9.10).

In my case I had out of memory exception:

Exception in thread "OfficeProcessThread-0"

terminate process

... 5 more

To ensure error will be at least logged I changed method to:

private void doTerminateProcess() {
try {
int exitCode = process.forciblyTerminate
(settings.getRetryInterval(), settings.getRetryTimeout());
logger.info("process forcibly terminated with code " +
exitCode);
} catch (Exception exception) {
logger.severe(exception.getMessage());
throw new OfficeException("could not terminate process",
exception);
}
}

Now - how I can resolve why out of memory happened?
Garbage collector is configured through environment variable:

export CATALINA_OPTS="-Xms512m -Xmx512m -Xloggc:/usr/local/tomcat/temp/
gc.log -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xincgc -
XX:PermSize=512m -XX:MaxPermSize=512m"

Can I check something else?

It's not an OutOfMemoryError, it's an IOException, caused by "cannot
allocate memory". In other words, it's not the JVM memory, it's the OS
memory.

Kind regards
