Getting C-level stack trace can hang on AIX

GemStone/S 64 Bit allows printing of the C-level stack trace on AIX,
using the procstack function.  The C-level stack trace is printed
when sending -SIGUSR1 to a GemStone process, or when printing stack
traces to the log due to low memory conditions, or during error
conditions.

AIX version 5.3 has a bug that causes the procstack function to
hang.  Customers on AIX version 5.3 should download and install
APAR IY83603.

This APAR is included in AIX 5.3 Technology Level 5, however,
5.3.005 has a separate problem, and should not be used.

Workaround

Install the APAR.  Avoiding sending SIGUSR1 or other conditions
that will cause a trace to be printing may help but are unlikely to
be sufficient.
