[Serusers] Serweb Error : 500 fifo_uac: no mem for hf block

[CURRO_DOMINGUEZ]

Hello
 
 I continue with my tests on SER. Things are going OK, so really 
 thanks. 
 
 I have this error in serweb. I connect as an user and go to phonebook.
 When I click on sip address of my contacts, I get this message on a 
 newwindow:
 
 500 fifo_uac: no mem for hf block.
 
 ¿Is this normal?
 
 And I have this problem too: I can't send IM from serweb. When I click
 on send, I get
 
 478 fifo_uac: Unresolveable destination (478/FIFO/UAC)
 
 However, the SIP clients are running OK.
 
 Again, thank you very much
 
 Curro
