perl problem

[RJ45]

Hello using imapsync to make a transition from imapuw to a cyrus server
make the imapsync perl process to die on FreeBSD 6.1 because it uses more 
than 512MB of memory.

this does not happen using imapsync with the same transfer operations on 
hte same mailboxes on a Linux fedora box the memory used also is less than 
512MB.

recompiling ther kernel of FreeBSD rising the memory to 1GB does not fix 
this at all. Seems like the perl process on FreeBSD explodes in memory.

How can I do to fix this issue, any hints ?

thanks a lot

Rick
