Hi all!
I have a problem with CentOS 4.4 and Communigate Pro 5.0.9. As our
user number grows, we are seeing "too many files open" error messages in
Communigate logs.
I spoke with Communigate tech support and they asked me to increase
the number of file descriptors which i did. I put 128000 as a script i
made to check Communigate open files reported as high as 99000. As i
checked the Communigate log file, it reported that it "sees" 1024
"available" file descriptors.
Reporting that to Communigate tech support, the guy answered:
"CommuniGate gets this number via getdtablesize() system call. Probably
in CentOS the table has a fixed size so you need to recompile the kernel
to expand it. Try upgrading CentOS to 4.5 (or whatever later version is
available) "
I'm a little afraid of upgrading the server right away, i don't want
to worsen the problem. Or maybe it's safe to do it. I dunno.
Is there anybody on the list that can comment on what the
Communigate tech support guy said about the "getdtablesize" thing ?
As usual, commercial support is just making things up. This one is easy to actually test.
#include <unistd.h>
#include <stdio.h>
int main (void) {
printf("current file limit: %d\n",getdtablesize);
exit (0);
}
Compile it, run it, viola!
===> Voila! (French is my first language! Trying to help for your
french here!)
$ gcc getdtablesize.c
$ ./a.out
current file limit: 134513392
(results will vary).
OMG! Exactly what i needed! It reminds me when i was coding C on a Sun
SparcStation 10 about 15 years ago!
I did compile the code and obtained exactly the same number.
Thanks a lot Garrick!
I just replied to the TS guy @ Communigate, i just can't stand to see
what will be his response!
Regards,
Guy Boisvert
