5.2.1 using heaps of memory for Perl Process

[Andrew Nelson]

Hi,

I've just upgraded from 4.9 to 5.2.1 and have a perl script
which runs for about 10 minutes roughly 20 times a day.  Since
the upgrade, the same process has started crashing with "Out
of Memory"..  It keeps building up, eating the swap then crashes.
The swap partition is the same size on the old machine but I don't
think it ever needed it.. (exactly the same hardware too).

'top'  shows the process alternating between  STATES: 'piperd',
'swread' and 'RUN'.

All the process does is uncompress some data (using the system
command to flow-tools) and inserts it into a MySQL database.

it's the same version of perl (installed with default FreeBSD install).

Can anyone suggest a fix?
Thanks,
Andrew.
