[Freeswitch-users] Strangely High CPU Usage on Idle FS server

[Anthony Matejcich B.Com]

HI guys

Relatively new to the FS world and have exhausted research online.

Running FS
FreeSWITCH Version 1.2.10+git~20130624T024915Z~8fd4994b0c (git 8fd4994 
2013-06-24 02:49:15Z)
On VMWare virtual machine with Debian6 and specs of 2 CPU with 1 GB RAM, 
50GB storage

Currently only running one client with very very low call usage until we 
have tested the FS server. Total of 30 calls and day
maximum and basically only running a simple IVR set up with 7 digit 
keypress prior to sending to Lua script for a simple calculation
and then delivery to mobile or landline in Australia.

System has been great for 6 months but issue arose around the 13th Dec 
13 - dmtf entries are being duplicated. A single kepyress
appears to register 2 of the same digit and is recorded as such in the 
CLI notes. Only happens about 50% of the time. Added a CPU to the mix
and it may have assisted with this becoming about 30% of the time 
showing the issue now. But that seems crazy to require CPU's given it
is such a small set up.

Reviews showed high CPU Usage via top command information. CPU usage for 
the FS process is sitting between 14 and 22%!
(constantly fluctuating) For the idle machine/with no calls coming in.
Thus %wa is fluctuating between 1 and 8% constantly.

There is no load on the server - but we did look at master logs and 
update core.db to the default <param name="core-db-name" 
value="/dev/shm/core.db" />

Very strange given the success over the first 6 months.

Can anyone help please with information or where to go? Would be greatly 
appreciated.

Anthony
