We get a similar message in one of our applications. I suspect that is is
due to a memory leak on the PC. It may or not be your application but
something else running on the PC. My solution is to reboot the PC before i
do any operations that may take a lot of memory or that has crashed
previously when I ran the application. Also when you run your macro close
all the unecessary apllications on the PC.

Hi Team,

I am using HSSfWorkbook to create work books using POI API. It has been
working fine. But whenever the date is more and when I try to upload XL sheet
it is giving "
Maximum number of fonts have been exceeded error "

Any pointers in this regard are appreciated.
Thanks in Advance
SJ
