tracing the source of a signal

[Brendan Corcoran]

Hi, Our java process on HP-UX is crashing with the below error.

The error indicates that the java process received an unexpected signal (signal 6).

Is there a way to trace who/what/where this signal came from?

ta,
Brendan

You could try 'tusc'

You can get an already compiled version from the HP Porting Centre.

use following option once you download tusc.
tusc -f -l -p -E -o /tmp/tusc.out command
