@Jaykah - if they repeat, is important to see how many times -- can you count how many error messages that contain the next texts are from start to out of memory logs?
``` authentication failed for got sip response 500 while registering ```
Something like:
``` grep "authentication failed for" /path/to/logfile | wc -l ``` Just be sure that the logfile has only the logs from startup to out of memory, not older logs.
