Hi all: thanks for the responses.
I should have done this in the beginning. I checked the status open returns. I
try to open 388 files, but it returned true(1) only 249 times (for the first
249 opens). So I guess thats the limit.
Also to make sure I am doing the right way, the following is how I am opening
the files
$AgentFH{$id} = *$name;
open($AgentFH{$id}, ">>$filename");
I am speaking to the system admin if he can bump up the limit to 1024.
Any other thoughts?
TIA
Ravi

Some systems use ulimit to put an upper limit on the number of open
files. And I believe that at least some perl releases have an overall
limit of 128 files at once.

How odd. Did you check for errors upon every open()? Perl should (if
warnings are enabled) warn you if you're using a broken filehandle.
You probably want the FileCache module, which lets your Perl code
pretend many files are open; it opens and closes filehandles as needed
so that your OS sees only a few files in use at any one time.
use FileCache maxopen => 16;
Hope this helps!
