I guess the real question is how do I determine the run away process
then stop it in an unix environment. It might be perl or mysql. I
don't want
to have to reboot each time.

Looks a lot like either an endless loop or a problem with
recursion, as your script is trying to allocate 452 megs of ram.

Thanks
it was a subroutine accidentally copied into the subroutine that was
calling it. probably a recursive nightmare.
But I'm stil looking for good techniques on how to identify processes
that run away.

Setting resource limits (size of VM per process, number of processes per
user, etc.) helps to prevent runaway processes from gobbling up all
available resources. Either they will die when they hit the ceiling, or
at least they won't grow further while you still have a useable system,
so you can examine what is going on.

HI=D7=AA
For a project I'm working for, I now manualy search Web for strings
"=2Eps.Z" (compressed postscript files).Normally these are found on FTP://
. Then I go page by page and download these files one by one,then
process them.
I need to create code that will do it automatically and download
found files .
I was thinking of something like 'WWW::Mechanize' .
Will appreciate advise on searching and downloading the found files -
possibly with some sample code.
Thanks

I've successfully used POD::WSDL to generate WSDL using Perl 5.8.x.
I've used that generated WSDL to create C# client stubs for Perl
web-services. I had to edit two of the namespace definitions though
<wsdl:definitions ...
xmlns:tns1="http://namespaces.soaplite.com/perl">
...
<wsdl:types>
<schema targetNamespace="http://namespaces.soaplite.com/perl"
I'm not sure if I could have avoided this by configuring POD::WSDL or
SOAP::Lite to use consisten namespace values.

My limited experience of web-services in Perl and Java suggests that
Perl can be an order of magnitude simpler to code. But it depends.
Marshalling complex objects seems slow in Perl (SOAP::Lite) but I've not
benchmarked it against Java. I think Java (6) really starts to win out
if you have to deal with digitally signed SOAP messages.
Since web-services in Perl means SOAP::Lite, the RPC/Encoded vs
Document/Literal issue may be something to consider if you *must*
generate a Doc/Literal service (though I suspect Doc/Literal-Wrapped can
be, er, simulated, using SOAP::Lite).
If you have complex payloads then Perl SOAP::Lite is least work if you
return properly constructed Perl objects. Constructing return values
using SOAP::Data gives you a lot of flexibility but is more work. I was
forced to do this to make the serializer consistently tag data types
(string, integer ...) instead of guessing based on value, some non-Perl
clients don't like it when a string "1" is given an "int" attribute :-)
At the moment, I'd prefer Perl for web-services of low to medium
complexity where the throughput is not high.
If I was more proficient in Java, I suppose my view might change.
