Cannot create large size excel file

[nafta]

Hi, I am using POI 1.11_dev version in a web application. it works fine all the
time if users are creating small size excel files . It also worked fine at the
first two weeks for creating large size excel files. However, it started broke
after two weeks, if users have a large job, writing to excel files hangs. For
small jobs, it's still working. Do you have any idea why this happens? Thanks.

When you mean larges file...Excel has a limit of 65,000 rows which could be your problem. Also you may also want to post this question on the POI mailing list...
