Thanks

Using the dbug statements is something I usually do, especially with CGI programs where I have not found a viable way to step through the code. Alas, this time, they did not help

I also usually look at the logs, both error and access, and this time, they didn't tell me anything I didn't already know. The Perl script simply stopped writing out the data once a limit of about 152 kB.

But I have a solution, as it were. I used MySQL to output the data directly to a file. I then used IO to slurp the data (in this use case, typically about 1 MB), and write that out. This works fine, and this makes the cause of the original problem even more puzzling as clearly Apache, as it is presently configured, is capable of sending a lot more data than it was.

Thanks again
