MobilePrint Temp file growth

Hi Everyone,

In the last 3 days, I've seen an issue on 3 of my print servers which are also Mobileprint Worker services, where the MobilePrint temp file has grown abnormally large (one was 24GB today) and does not reduce in size. We had to stop the Print Spooler service in order to delete it. Has anyone else seen this behavior?

We're running Uniprint 9.1 Service Pack 1, Mobileprint 2.3, with no changes since updating to SP1 and MP 2.3 in July. The print servers are running Windows Server 2012 R2, and were most recently patched on 10/26/19 with the October 2019 updates. None of the patches seem to touch Print spooler, but I could have missed something.

Gene

We've had the same problem. It seems to be related to the 'small' pdf actually being huge and the server trying to render it. We're moving our Mobile Print temp folder off of the C drive at our next maintenance to help alleviate the issue of running out of space on the C drive.

  Hi Mari,
  Thanks for the reply! Where is the setting for the MobilePrint temp folder? I looked for one, but I couldn't find it.

    Hey Gary,
    Unfortunately, there isn’t a setting per se, you have to manually move the folder by adjust the properties and pointing it to the new location (and then reboot the server).

What is the path of this temp folder? We are in the beginning stages of implementing Mobile Print on campus and I'm curious about our current folder size.

  Based on my notes, Mobile Print makes use of the windows temp folder when processing a file. So we offloaded the windows temp folder to another drive in our development/test environment. So C:\Windows\Temp is now E:\Windows\TEMP

    Thanks Mari! I was hoping not to move the entire C:\Windows\temp folder, but that seems to be the only way to go. We'll be discussing that same change with our server infrastructure folks this week.

  Hi Kayla,
  
  This is something we really hadn't seen before. In general, the MobilePrint Temp file gets created and deleted as jobs are being processed by the MobilePrint worker service. As Mari described, some jobs became huge in the rendering process. In our case, on several different servers, the temp file did not clear out. It just got bigger, though in some cases, the size went up and down, but never went away, or below 5GB. On a couple servers where we had about 20GB-30GB of free space to begin with when we received alerts of the servers running out of disk space. We've been running MobilePrint since 2014, and I don't recall this being an issue before. Had we not addressed it, we the Temp file might have eventually filled the C:\ and caused us major problems.
  
  I was hoping to just move the location of the location of the MobilePrint temp file to another drive, but since we can't do that, I'll probably follow Mari's lead and move the entire c:\windows\temp folder to another drive.

    Thanks for the additional information Gene. What size C drive do you have on your Mobile Print server running the worker service?

      Hi Kayla,
      
      Our C:\ drives on our worker servers are 50GB to 60GB. We started at 30GB years ago, but expanded as the C:\Windows\WinSXS\ folder grew.

      We have a round robin API with five servers participating as worker servers and it looks like our C drives are normally 100G with 50G free, but we had to bump up the space on one of the servers due to the mobile print issue. That server has a 150G C drive.
