Hi Oscar

This error typically identifies 1 of 2 things, a memory or a disk issue.
Memory
You already checked if the processes are close to 4GB (ie. for 32 bit processes), please be aware that most processes will crash when they reach 4GB. => has a crash occurred recently? (check via C:/Skyline Dataminer/Logging/Crashdump)
It’s better to check for a memory leak in the SL* processes. I would focus on the agent hosting “SR1.TMDR.PROD” and on the bigger processes (SLDataminer, SLNet, SLDMS, maybe also SLProtocol)

Disk
Have a look if the C drive is running short of free disk space now or if it did go without free disk space recently
=> if the server goes without free disk space, then the DMA must be restarted.

NOTE
By “checking for a memory leak” or “check the C drive”.
I mean look at this trending on the agent that hosts element “SR1.TMDR.PROD”, via its Microsoft Platform element.
Having a Microsoft Platform element per agent, with configured alarm and trend template, is a best practice in order to monitor the DMS.

Now if the above didn’t help you, we have again 2 options.

• Restart the DMA or reboot the server, this will most likely resolve the issue. Assuming this is just a single isolated occurrence.
• This is a recurring issue. Then it’s important to gather the needed information and forward to our techsupport team.
  => When you see the error occur again, as soon as possible, grab a LogCollector package, incl. memdumps of SLNet, SLDataminer, SLDMS.
  That should be a good starting point to investigate the issue
