[Freeswitch-users] Getting WTF1..N messages in the fs log

Hi, I am testing FreeSWITCH on Xen Linux VPS sever. FreeSWITCH Version 1.0.head (git-7566575 2010-05-26 10-45-52 +0200) Linux: Ubuntu 9.10. When I view the log using ./fs_cli I can see periodic messages in the log: WTF1 WTF2 WTF3 WTF4 WTF5 WTF1 WTF2 WTF3 WTF4 WTF2 ... Looks like FreeSWITCH works properly, however these messages make me warn. I never seen these messages on the other servers - could you please advise what can I check? Thank you, Vitalie
