Meaning of drcb_bqe

I have another challenging question which may shed some light on my long checkpoint problem: What does the abreviation "drcb_bqe" stand for? Here's the context of the question. NOTE: Only the pertinent lines of the onstats are shown. onstat -l has the following entry in it: Buffer Waiting Buffer ioproc flags L-3 4004e754 0x1 0 onstat -u shows the iproc address belongs to this thread: Userthreads address flags sessid user tty wait tout locks nreads 4004e754 Y-BPX-- 3336 jdoe 13 400a1648 0 1 553 The thread is waiting on something at address 400a1648, which is not a lock or a latch since the tout is showing 0. So what is associated with address 400a1648? onstat -a shows the following info: Conditions: cid addr name waiter waittime 70 400a1648 drcb_bqe 0 -1 So what does drcb_bqe stand for? I try to keep my queries on the net to a minimum since I know that everyone else has other things to do, but this one is definately not in the manual and has really got me stumped. ==================================================================== Harold Luse Phone: (970) 491-4120 Veterinary Teaching Hospital Fax: (970) 491-1275 Colorado State University Pager: (970) 229-8173 Fort Collins, Colorado USA E-mail: hluse@vth.colostate.edu ====================================================================
