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:
OS version: CentOS release 5.4
the cpu info is:

the mem info is:

the out  put of the command top is

the number of calls when I made the test was:
5 total.

the out put of gcore and gdb:

number of sofia's profiles:
5 sofia profiles and 1 alias
number of calls that I want:
30  simultaneous calls

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