[asterisk-users] 786 000 files limit Centos 7 - Asterisk keeps complaining
Hi Guys
I keep getting messages in the Asterisk 1.8.11.0 CLI that there are not
enough file descriptors available on my Centos 7 box.
I also get regular error messages that RTP connections are failing due to
bad file descriptors.
I have already edited /etc/sysctl.conf by setting fs.file-max to 786 000
files, and running sysctl -p afterward.
I have also edited /etc/security/limits.conf and entered
* soft nofile 786000
* hard nofile 786000
and rebooted my system.
When I ge the Asterisk error messages in the CLI that there are not enough
file descriptors, I immediately ran
lsof | wc -l
and I only get around 100 000 files open - while my limit is 786 000 - yet
still Asterisk keeps complaining.
I have also edited /etc/asterisk/asterisk.conf to have
maxfiles = 786000
and restarted Asterisk / rebooted, but this has no effect.
Why does Asterisk 1.8.11.0 complain that there are insufficient file
descriptors when my limit is 786 000 and the kernel itself states that only
100 000+ handles / decriptors are in use at the moment Asterisk is
complaining about insuffiecient descriptors?
Anybody else ran into this?
Thanks
Stefan

Responding to Matt Riddell, M Shokuie, A J Stiles, and Telium Support (all
below)
Thanks for the suggestions, but a separate gateway is a problem in the
design as the configuration is basically:
Carrier --- PRI --- Asterisk (with failover) ---- Legacy PBX
|
- SIP / IAX2 -- our service or remote office
As this is already acting as a gateway adding another box to the mix seems a
bit over kill (unless I can embed it and the asterisk PBX into a 2 U pizza
box). But since most gateways are designed to be used for fail over servers
/ PBXs not lines I am not sure that this would benefit us.
So far I have found 1 company that seems to have a gateway card and that is
the beroNet PCI / PCIe Gateway Cards which they say has the card level
failover. I will update the list should this meet the use case.

If you place an ESL PRI A/B switch on either side of the Asterisk server you
can easily bypass the Asterisk server, or place it inline with the PRI link.
You can also chose to TAP the lines as noted above, but you have to ensure
that both PRI cards don't go live at once...(if I understand that product
correctly).

Hi All,
(Again cross posting, so sorry if you see multiple copies)
Ok. as we are getting closer to Astricon I am sending out an update to see
who is interested so we can book the trip with transportation.
As this year Astricon is in Orlando, and most of us are tech geeks in on
form or another, we are trying to organize a road trip to see NASA's Kennedy
Space Center.
We are looking at doing this the Friday (Oct. 16) after Astricon so as to
enable those working the con to attend.
Cost per person will be *$121*.
This is for The Kennedy Space Center Tour with Dining with an Astronaut
which includes
1. Roundtrip Transportation from the resort
2. Admission To Kennedy Space Center Visitors Complex
3. Space Shuttle Atlantis
4. Shuttle Launch Experience
5. Angry Birds Space Encounter
6. Apollo/Saturn V Center
7. General Bus Tour
8. I-Max 3D Movies
9. Admission To Astronaut Hall Of Fame
10. Lunch with an Astronaut (you get to also ask questions, get
autographs, and have a picture taken)
So please let me know if you are interested, as we get closer we will
discuss total price and how people can pay it.
Looking forward to seeing you in Orlando in October.
Eric

[asterisk-users] 786 000 files limit Centos 7 - Asterisk keeps complaining

It sounds like you have a file descriptor leak (not being closed when finished with). You might also want to look at the output of lsof (or at least some of it) to see what all these file descriptors are pointing to, and whether it is indeed Asterisk that is consuming them. If it is Asterisk, it's quite possible, even probable, that such a leak has been found and fixed, even in the 1.8 series. 1.8.11.0 is rather old - the latest is 1.8.32.3, so it would be best to update to that version and see if the problem persists.
