Have you looked at a debug log when this is happening to see what FreeSWITCH thinks is going on?

Hello,
Freeswitch version: 1.6.11 Number of registration on my switch: 270+ Ram: 4 GB, 1 GB is free; 64 bit debian 8
I am facing this issue, where some time i am getting continuous INVITE registration requests but freeswitch not responding to it
and sometime i am getting 503 service unavailable
I have gone though https://freeswitch.org/jira/si/jira.issueviews:issue-html/FS-6589/FS-6589.ht... <https://freeswitch.org/jira/si/jira.issueviews:issue-html/FS-6589/FS-6589.html> as well but not finding much helpful.
here is the sip log for the same, if you want to go through. http://pastebin.com/PXz277XD <http://pastebin.com/PXz277XD>
Is RAM upgrade a solution? or any other?
