  ****************************************************************
  When formatting certain trace entries, the MQ dump formatter
  calls CSQWCNAM to get the name of the routine which wrote the
  trace entry. An error in CSQWCNAM resulted in the working
  storage obtained by this routine not being correctly freed,
  eventually exhausting the storage available to IPCS and
  resulting in the S878 abend.
  

Problem conclusion

Temporary fix

Comments

• CSQWFMTC is changed to correctly free the working storage
  obtained when CSQWCNAM is called by the dump formatter.
