Is there a chance you're running out of memory, as in RAM?

Hi,

I have a problem with sympa. I have created 500 lists and they don't
work. Only work 250 more or less.

How many files open every list?
I think that I have a problem with file descriptors at level of the
operating system. My OS is:

Solaris 8
4 Gb RAM.
2 CPU UltraSparc III.

# ulimit -a

core file size (blocks) 0
data seg size (kbytes) unlimited
file size (blocks) unlimited
open files 8192
pipe size (512 bytes) 10
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 29995
virtual memory (kbytes) unlimited


The error in /var/adm/messages is:

Hello,

my Solaris has 4 Gb. RAM. It isn't possible.

I have installed on a box Linux with 256 Mb RAM and 500 lists and work fine. Why?, What is the difference?.

I had such problems with some other programs that have been compiled by gcc/32bits.

This is known bug on Solaris : gcc doesn't allow more than 256FD's....

There is 2 way to avoid that : recompile your perl with gcc under 64bits or compile it with Forte CC (you can get a free copy for one month for that.)...
