Operational Errors

Last updated 4 months ago

Occasionally it can be useful for debugging purposes to check the Realm Object Server logs. Realm Object Server produces two specific classes of error and warning diagnostics that may be useful to system admins and developers.

Error Message

Solution

Failed to accept a connection due to the file descriptor limit, consider increasing the limit in your system config

Increase the file descriptor limit on your machine. Instructions on how to do this can be found here. In general, you'll want to set this well above the number of realms on your server (3-5x the number of realms is typically a good place to start).

mmap() failed: Cannot allocate memory

Consider increasing the amount of memory available on your server. If you believe that your server has ample resources, please contact us.
