iPrint process consumes a lot of memory, normal?

Hey guys,

the iPrint Advanced installation on our OES 2018SP3 consumes a lot of memory... Is that normal? We are running around 20 printers, on 100 Workstations with 150 users...

This is top sorted with memory consumtion... 

Any ideas where to check?

Thanks in advance

  • Hello Gonzalo,

    thanks for your reply...

    Its sounds to fit perfectly for my problem but unfortunatly, the properties section is already there with the given entries... Any other ideas? 

  • then it could be normal. java is a heavy beast. What do you get with this command:

    ps -eo pmem, pcpu,pid,user,args | sort -k 1 -r | head -15

  • Sure, there you go...

  • java being a heavy beast is an understatement.

    ps -eo pmem, pcpu,pid,user,args | sort -k 1 -r | head -15

    thank you for this command,  very useful once we get the extra space out of it after the first comma that sneaked in there.

    ps -eo pmem,pcpu,pid,user,args | sort -k 1 -r | head -15

  • So i'll add couple more gigs of ram and watch it?

  • i do not see any problem with your server. Not sure why you want to add more memory. 

  • Why are you doing that?  To what end?  Is there a problem you haven't told us about?

    It isn't like your swap is getting consumed much at all, and that is what I usually use as my driver for if more RAM is needed.  A common part of my health check is the 'free -m' command, and as long as swap stays well under half used, I don't worry about memory usage unless something else strongly points to it.  Using lots of a plentiful resource is not a reason to just add more.

  • Because the server acts snappy when MEM free runs low... Also the server is quite old and running on HDDs, so swapping is really slow...

  • snappy

    Normally snappy implies fast and quickly responding, perhaps too fast.  I suspect that wasn't what you were trying to say from the tone of the rest of what you wrote.

    For an iPrint only server, the question is what humanly perceivable performance issues are there that can be directly attributed to the server?  Also would be worth checking the drive system to make sure it doesn't have any issues (such as a drive down) as all print jobs do get written to disk as part of printing, so any slow-downs there would be a notable impact way beyond anything those memory numbers you shared would indicate.

    Have you used ganglia to see the memory trends?  http://serverIP/gweb   

    I have a client of about the same size, with their iPrint vm working just fine with 4GB of ram, even with the charge-back mechanisms in place.

  • Hey Andy,

    lol Joy, no that wasnt what i ment and thanks for clearing that up. Now it makes totally sense that other people reacts weird when i used the word like i did...

    Its not an iPrint only server... Its the main server hosting NDS, NSS, DHCP, DNS, LDAP and iPrint Advanced...

    I didnt check the ganglia service but i will...

    I think i will move the iPrint Service to its own appliance
