LO80524: ROUTER CAUSES CPU SPIKES UP TO 100% DURING CD -> MIME CONVERSION

APAR status

• Closed as user error.

Error description

• When router does CD -> MIME conversion, all header fields are
  checked to see if the content needs to be encoded. If any field
  contains character
  "; (semicolon)
  ", ", (comma)
  ", " \n (linefeed)
  " or " \r (carriage return)",
   it will be converted to UTF8 and encoded as Base64. This
  causes the Domino server to spend a lot of time trying to
  convert and to encode what is the main reason that the server
  seems to hang and to consume all CPU. In customers case the
  issue was caused by some machine generated mails which used a
  complex form, containing a lot of header fields meeting the
  conditions discussed above.
  

Local fix

• Either use a standard template or rework the customized mail
  template to avoid saving script or larger content in the
  headers.
