[Koha] Sip Server stops

[Alberto Branco]

Hi all,

I'm having a problem with koha sip2, everything seems ok and I'm able to
login, but after the service is running for a while (it varies) the service
stops responding.

And I get this message when I try telnet:

telnet xxx.xxx.xxx.xxx 8023
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx.
Escape character is '^]'.

After I restart the service everything comes back to normal.

Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx.
Escape character is '^]'.
login: myuser
password: mypass
Login OK.  Initiating SIP

There are no errors  in sip-error.log

This is my SIPconfig.xml

<acsconfig xmlns="http://openncip.org/acs-config/1.0/">
<!-- above address gets nothing, it's just a namespace -->
  <error-detect enabled="true" />
<!--
  Set Net::Server::PreFork runtime parameters
  syslog_ident will identify SIP2 Koha server entries in syslog
  For OpenSolaris, add: syslog_logsock=stream

  <server-params
    min_servers='1'
    min_spare_servers='0'
    log_file='Sys::Syslog'
    syslog_ident='koha_sip'
    syslog_facility='local6'
  />

  <listeners>
    <service
      port="8023/tcp"
      transport="telnet"
      protocol="SIP/2.00"
      client_timeout="0"
      timeout="60" />

    <service
      port="localhost:6001/tcp"
      transport="RAW"
      protocol="SIP/2.00"
      client_timeout="600"
      timeout="60" />
<!--- client_timeout times out active connections which have not received
     input from the client. Many persistent connections will send a status
request
     every 5-7 mins so setting this to less than that will add instability
to the connection
     if explicitly set to zero, no timeout is applied to the connection.
     NB the parameter timeout applies to the login process only and should
be set to a lower value
     to time out failed connections

The implementation attribute is actually used to find the code to run,

          <policy checkin="true" renewal="true" checkout="true"
