[Serusers] Question:Jabber server lost

[lihongbin]

Hi,

  When using the Jabber Gateway, I get the following error from time to
  time:

  ERROR: Connection to Jabber server lost. You have to login to Jabber server
  again (join again the conferences that you were participating, too).
  sip_to_jabber_gateway says:
  INFO: Your are now offline in Jabber network. Thank you for using SIP-Jabber
  gateway.

 How to solve this quetion and if it is possible to  avoid them?

  Thanks

  jenny
