Am getting alf-backstop-*.dmp Files?

o_o_ — Mon, 24 Aug 2009 02:18:02 GMT

Hi, I am new to Alfresco and have installed it using the stack installer on Windows XP. I start it using alf_start.bat and stop it using alf_stop.bat. It seems every time it starts and stops it dumps a file of the form alf-backstop-*.dmp. Is this Ok i.e. is this the normal behavior? If yes then

No its not normal. What is happening is that shutdown is not working correctly, but Alfresco has shut down anyway. And produced a dump so we can see which threads are causing the problem.

Please raise a JIRA ticket and post the contents of the dump file.

Thanks mrogers. I guess I should post the Issue at https://issues.alfresco.com/jira/browse/ALFCOM (I have never opened a JIRA ticket before.) Please let me know under which component do I put it in the list given in the above URL?

Thanks,
O.O.

I have the same issue, every shutdown creates a backstop-log, which typically looks like this:

I'm not really sure how to interpret it.

The server is running CentOS 5.3, with Java 1.6.0 update 13 and Alfresco 3.3.0 revision 15634.

Edit: However, this behaviour has been seen with prior versions too.

Hi,

I just posted this Bug on in JIRA ALFCOM-3334 at https://issues.alfresco.com/jira/browse/ALFCOM-3334 .

Gronfelt,
I hope you could post some of your alf-backstop-*.dmp and log files. Since you are using the 3.3 version it might be more incentive for them to fix this.

O.O.

I've added my latest dump-file to the JIRA issue.

Hi,
We are using alfresco version 3 on linux RHEL5 64 bit machine java jdk1.6.0_25.
I am using stopWebLogic.sh and startWebLogic.sh to stop and start the alfresco.
The alf-backstop-20150609004041.dmpand alf-backstop-20150609105951.dmp files are created.
Please help to analyse the issue.

Thanks lot.

It's just alfresco not shutting down correctly. You may safely ignore it.

The actual underlying problem was fixed many years ago.

Re: Am getting alf-backstop-*.dmp Files?

dipti — Fri, 12 Jun 2015 04:55:38 GMT

Thanks for your reply!!

The issue we are facing is that we are having alfresco setup on 2 different linux machines and both are using same alfresco metatdata repository(alf data,upload).
The alfresco server is running and we are able to use it in our application to do attachments.
Where as,on second machine the alfresco console is running state but we are not able to do login through admin user(and other user also) and also not able to do attachments through this amchine alfresco.
Also ,the database is same for both the alfresco.

We are not able to perform index recovery (using fill recovery mode in custom repoitory poperties) on second machine as it gives error.
Below are the logs:
