Hi!
I have had a user account for my Mango software for a long time.
But now it seems to be gone, is there a need to register again ?
I had an account in infiniteautomation.com(and prior to that) the forum cridentials are working.
I have been running Mango sinse prior to version 2.

Hi !
I am installing Mango on a old PC with a fresh UBUNTU installation 16.04.
After Java installation according to Installatiob section in Documents page I have some starting up issue
See attached text, what do I do?

@phildunlap It looks like the same issue i have posted on my mini mac
I got the java to hang.
Please provide the same info and post a answer on the forum what happens

I can not manage to start my Mango after a possible power failure on my Mac Mini that hosts the Mango software. It has been running for several mounts witout any major problems.

I add now when I saw anothet topic that it was after i started a upgrade of the software the restart hanged and now it is still so after som days and after a power cycle of the mini mac. So there is no power failure causing this.)

The " ma start " does not complete, the java icon does not show up, abd a java process is using 99% of processor time for up to 9 hours until i forced the process to shut down.
At the Command prompt following was printed then:
"ma-start: MA started with Process ID: 678

What is the problem?

I found the bad guy !
A Cron Job create all the files in /var/spool/exim4/input.
When I disable this task, the folder is quiet .
But why is this job there ? and what is it suppose to do?

New files are created all the time.
There two different contents one is:

The other has following content:

I have now created an empty log.txt file in the missing mango-backups folder,
lets see if this does the trick...

I have now removed the files in the /var/spool/exim4/input.
Now the resources is back on track, but still what is creating the files?

After :

Then I am able to run basic Webmin functions, but what is creating the problem?
I have tried no to run apt-get purge and autoremove but there is nothing to clean out.

Now I work with following command.
$ for i in /*; do echo $i; find $i |wc -l; done
This lists the folders and inode number.
and I fount that /var had over 300k nodes
I will dig deeper on where exactly

What is creating the files in /var/spool/exim4/input ??
