[Orca-users] Memory leak?

[Borja Marcos]

Hi,

I'm using Orca snapshot r535 on FreeBSD 7/amd64 (the 64 bit version).

This machine uses Orca for some Solaris systems, FreeBSD (using  
devilator) and some Linuces using procallator.

And I've found that Orca is getting an outrageous amount of memory

The reason for so many processes is that we have them divided into  
platforms, operating systems, etc.

The system is FreeBSD 7,

RRDtool is version 1.3.0, and the rest of the Perl packages:

p5-Data-Dumper-2.121 Stringified perl data structures, suitable for  
both printin
p5-Math-Interpolate-1.05 Perl routines for data sets interpolation and  
interval sear
p5-Storable-2.18    Persistency for perl data structures


Other than these, I've used the packages provided with the Orca  
snapshot.

Any clue? Anything to check in order to locate the leak?



Thanks,






Borja.
