[Orca-users] Re: Out of memory error

[Blair Zajac]

Which version of Perl are you using?  Perl never gives memory back to the OS.

I try to make sure that Orca releases all references to objects that contain
memory, but this may not be done well enough, or there may be circular
references that never get cleaned up, or problems with Perl.  It's hard
to say.

Does anybody know how to determine where Perl memory usage is tied up?

If you can restart Orca once a week or so, that would work great.
