  TQE Quota and Kernel-mode TQE Processing? 
 The Question is:
 
I have a process which keeps running out of Timer queue element quota using
 V7.3-1. This behaviour was not observed under V7.1-2. Some timers are set
 using EXE$ALLOCTQE and EXE$INSTIMQ. I see there are new fields (TQE$V_TQTYPE,
 TQE$V_ASTNODEL). What is th
e meaning of these fields, and must I set them before calling EXE$INSTIMQ?
 Could this be the reason of the quota problem? With SDA I see several timer
 entries with the ASTNODEL flag set.
 
 The Answer is :
 
  The internal implementation of the timer queue was changed from a linked
  list to a tree with OpenVMS Alpha V7.3-1, and applications directly
  accessing the associated kernel-mode data TQE structures will need to
  be evaluated for compatibility with the implementation.
 
  The TQTYPE bitfield is the type of TQE: timer, subroutine, wake, etc.
 
  The ASTNODEL flag controls whether or not the TQE/ACB is deleted
  after the AST delivery.
 
  For details of the internal implementation, please see the OpenVMS
  source listings.  Order numbers are included in the OpenVMS FAQ.
