in reply to Perl Memory problem ...

If you give us more information we should be able to help. Meanwhile, these old nodes might give you a clue as to what your problem might be:

General Areas to consider when faced with a Memory Leak

  • Stability: Once your process grows to a certain size, does it stay there, or does it grow further over time?
  • Large CPAN Modules. Are you using any?
  • Circular references. See Eliminate circular reference memory leak using weaken (Perl Maven)
  • Scoping.
  • File/Database handling.
  • Tools. Try one or more from the following section.

Perl Tools and Advice

  • As pointed out by dave_the_m: "once the perl interpreter has exhausted all memory, there's very little it can do. There is a reserved fixed buffer to allow it to display the OOM error itself, but doing anything complex like displaying a Carp::confess()-like stack backtrace would require many memory allocations to generate the display, all of which would themselves fail".
