Local fix

Problem summary

• USERS AFFECTED: All using LLC links.
  
  PROBLEM DESCRIPTION:
  A delay is seen receiving frames on an LLC2 link. The delay is
  typically 61-62 seconds.
  
  PROBLEM SUMMARY:
  If setting a certain timer (streams timeout) fails, then this
  delay can occur because CommServer fails to quickly complete
  work that it has outstanding. The result of setting the timer
  was not checked, so the failure was not detected.
  

Problem conclusion

• Code has been modified to handle this error case and ensure that
  a fast timer is always available to complete outstanding work
  when the system is busy.
  

Temporary fix
