thomas.schubert commented on Wed, 19 Jul 2017 21:23:31 +0000: Hi sallgeud, Sorry for the delay getting back to you. From the log files, I can see that these crashes are the result of hitting a "Too many open files" system limit. We're aware that these replica sets may have hundreds of thousands of active data handles, as a result, unfortunately, this type of error is not unexpected. As you're aware, we have work scheduled to reduce the number of open files required for your schema and workload. For now, I would recommend reconfirming that your ulimits are appropriately set. Kind regards, Thomas sallgeud commented on Wed, 19 Jul 2017 16:53:46 +0000: Uploaded. It happened in 3.4.5 for us in the previous few days, so I've uploaded the 3.4.5 logs as well. sallgeud commented on Mon, 10 Jul 2017 19:29:55 +0000: Oops.. nm. See it now sallgeud commented on Mon, 10 Jul 2017 19:29:37 +0000: Sure. Send me over the secure upload Link thomas.schubert commented on Mon, 10 Jul 2017 17:41:59 +0000: Additionally, would you please provide the diagnostic.data, as that may help us rule out some other theories that would explain this behavior. Thanks again, Thomas thomas.schubert commented on Mon, 10 Jul 2017 16:04:21 +0000: Hi sallgeud, Thanks for the report, to help us investigate would you please upload the complete log file that includes the fassert? I've created a secure upload portal for you to use. Kind regards, Thomas
