    SIP parse errors cause the SIP Container to enter an endless
    loop
    

Problem conclusion

  • The problem is occurring when the
    number.of.parse.errors.allowed custom property is applied and
    set to -1.
    A fix was delivered into the SIP Container so when a malformed
    message is detected, the SIP Container discards it.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.16 and 9.0.5.0.  Please refer to the
