Decoding Mutex (EFWM) States?

» close window

The Question is:

 
I have a process going into a MUTEX state and need help determining the cause.  \
The EFWM value is:
EFWM = -2115953792   Hex = 81E11B80  Octal = 20170215600
 
Following are other Process Quotas:
  WSQUOTA = 32768   Hex = 00008000  Octal = 00000100000
  WSSIZE = 16384   Hex = 00004000  Octal = 00000040000
  PPGCNT = 7616   Hex = 00001DC0  Octal = 00000016700
  GPGCNT = 2592   Hex = 00000A20  Octal = 00000005040
  WSEXTENT = 544288   Hex = 00084E20  Octal = 00002047040
  BYTLM = 97696   Hex = 00017DA0  Octal = 00000276640
  TQELM = 10   Hex = 0000000A  Octal = 00000000012
  TQCNT = 0   Hex = 00000000  Octal = 00000000000
  STATE = "MWAIT"
  EFWM = -2115953792   Hex = 81E11B80  Octal = 20170215600

Is it BYTLM, TQELM, or something else?
Thanks,
 


The Answer is :

FFFFFFFF.81E11BFC   JIB$L_FLAGS                     00000002
 
FFFFFFFF.81E11BB8   JIB$L_TQCNT                     00000000
FFFFFFFF.81E11BBC   JIB$L_TQLM                      0000000A
 
QED, TQCNT is depleted.
 
If the process needs to have more than 10 outstanding TQEs then increase
the limit, otherwise you're looking for a leak.
