    -----------------------------------------------
    If multiple Traveler threads invoke NativeAccess.isDiskBusy()
    simultaneously, the underlying Domino code might abend because
    they calculate the time difference between calls, and use that
    in some calculations, and abend if it is zero.
    

Local fix

  • Domino APAR LO88473 will also prevent the crash.
    

Problem summary

  • Traveler server crash when calling API call near simultaneously.
    

Problem conclusion

  • The IBM Traveler server has been updated to synchronize the API
    calls so they are not occuring at the same time.
    

Temporary fix
