1527.0. "hung up waiting for malloc mutex()" by HYDRA::BRYANT () Wed Apr 16 1997 15:20
This is from our friends at Software.com. Does anything stand out here? They
are running DU V4.0b.
THanks.

| 1527.1 | .0 set hidden because it referred to unreleased patch code | PTHRED::PORTANTE | Peter Portante, DTN 381-2261, (603)881-2261, MS ZKO2-3/Q18 | Wed Apr 16 1997 16:10 | 9 |
| Folks,
.0 was hidden because it was referring to a problem in code a test version of an
upcoming patch. The team felt that this would cause more confusion that it was
worth.
Thanks,
-Peter
