OOM and MailContentTransformer Error

alftier — Thu, 25 Nov 2021 12:08:58 GMT

Hi,

My company has a very old version of alfresco:
Alfresco 2.1.0-482 on JBoss 4.0.4.GA.

Recently we are having OutOfMemory issues that are forcing us to restart the service.

Analyzing the logs, the only error of the current year started to appear on 08/24/21 and its flooding the log file (I don't know if this is related to the oom)

I have only found one reference to the error :

https://hub.alfresco.com/t5/forum-archive/r%C3%A9solu-erreurs-r%C3%A9currentes-error-org-quartz-core/td-p/104021

It seems to be related to the outlook message transformer, but I do not know if it is safe to disable it, nor how to do it, since the configuration xml is packed in the war:

# grep -ir "transformer.OutlookMsg" *
server/alfresco/tmp/deploy/tmp1069080629325672482alfresco-exp.war/WEB-INF/classes/alfresco/content-services-context.xml:   <bean id="transformer.OutlookMsg"

Can the MailContentTransformer error be related to the OOM?

I appreciate any help, we are trying to connect jboss 4 to visualvm to try to get the graphs out of heap memory, but it is an old system and we are having a hard time finding documentation on how to manage it.

We are also having trouble pulling a heapdump (I'm a sysadmin, I don't understand too much java).

Thanks in advance, best regards
