Error description

  • SCP log target may cause system hang if the SCP server is
    unresponsive during time of file upload.
    
    The appliance may remain in a hung/wait state for up to 130
    seconds before it recovers and resumes processing.
    The log may show successive inactivity errors during the time
    of the hang:
    
    system,error,,,0,,0x80400025,,,"Watchdog system detects no
    activity for at least 49 seconds"
    
    system,critic,,,0,,0x80400025,,,"Watchdog system detects no
    activity for at least 50 seconds"
    
    
    Also, once the appliance recovers, the following log target
    errors may be seen at the end of the inactivity errors:
    
    [system][error] logging target(scp-log): tid(415730367): File
    not found.
    
    [system][error] logging target(scp-log): tid(415730367): Log
    upload of target scp-log failed.
    

Local fix

  • Use Syslog log target instead.
    

Problem summary

  • Affected are users of all firmware releases up to and including
    version 5.0.0.x using log targets with SCP or SFTP upload
    method.
    
    SCP/SFTP log target may cause system halt if the the
    target SCP/SFTP server is unresponsive during time of file
    upload.
    
    The appliance may remain in a wait state for up to 130
    seconds before it recovers and resumes processing.
    
    Fix will be provided in a next major release. No formal fix is

Problem conclusion

Temporary fix

  • The safest workaround for the problem is to use upload method
    other than SCP or SFTP.
