Re: [Wrapper-user] java application is failing to start on HP-UX

[nehamunipalli MS <neh...@gm...>]

Hi,
I did enable debugging for the wrapper. However, i am not getting any log
messages about which process is sending the signal. From the previous logs
before enabling debug was enable there were log messages that there was a
SIGKILL. This time after enabling debugging I am not seeing even that
message. What I want to know if this is happening because the signal or due
to some other reason. Please let me know if there is any other way of doing
the investigation.

This is happening on a HP-UX 11.11 host.

Thanks,
Prasanna
