Seems like you system is under SIP brute-force attack. Somebody is trying to break into your freeswitch box. Just find that user's ip and block it in IPTables.

If problem persists and hacker comes from another IP then you probably need to configure Fail2Ban service.

Thank you.

Hi all,
 This days am experiencing a problem with Freeswitch: it seems that it needs more hardware resources and voicemail don't work any more and it make a long delay to process call transfer. should I compile the last version to revolve the problem or try to increase hardware resources? I notice that I have anther instance of FS running fine in the same conditions. 
I tried to collect the maximum information that I can:

number of sofia's profiles:
5 sofia profiles and 1 alias

I want also to notice that I get all the time some warning messages like
