[Asterisk-Users] What would cause a high memory usage in pbx_spool.c ?

Hi,

After only 4 days I have 107472352 bytes in 46007 allocations in file 
'pbx_spool.c'

And top shows me that asterisk is using 153m virtual memory and 141 res 
memory... Only completely stopping asterisk and starting again will free 
up the memory.

What could be causing this?  I did read something about call files and 
variables in the past, but that was a long time ago. I do have to 
process .call files but not that many...

Could there be a memory leak in pbx_spool.c, how can I help troubleshoot 
that?

Thanks
Walter.
