Memory leak in Perl subagent?
Jon Walton
I have written a subagent in Perl. I am quite happy with the results,
although there seems to be a memory leak related to setOID() and/or
setValue().
Furthermore, when I run the example script provided at:
http://www.net-snmp.org/tutorial-5/toolkit/perl/perl_module.pl
I notice the same behavior. The footprint of the perl subagent
continues to grow with every GET and/or GETNEXT, until it eats up all
system memory. If the subagent is left to run without being queried,
it does not grow in size.
Does anyone know what might be causing this and how it can be resolved?
I am running Net SNMP 5.1/ Perl v5.6.1/ Linux 2.4.23
Regards and Thank you to the developers for adding this Perl support.

I'm quite happy that! I haven't gotten a whole lot of feedback about
it.

There certainly could be some memory leaks. I sure wish that
debugging the Perl/C interface mechanisms was easier than it is. The
one thing you might try to do: rather than run it as a sub agent
run it directly as an embedded module within the agent instead. Then,
run the agent using valgrind to help you debug where the memory leak
might be.
