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.
This is almost certainly the same as bug 15375. Have a look at that.
