Open Stack

What do you see if you run

mysqladmin processlist

I hope it doesn’t also give the same error (but that may be what you see).

Hi Jay,

Thanks for your reply.

I'm not able to use mysql command line.
$ mysql
ERROR 1040 (HY000): Too many connections
$
Is there any other way to collect the information?


Thanks,
Nader.

Hi All,

I am seeing 'Too many connections' error in nova api and cinder when when installing openstack using the latest..
The error happens when launching couple of VMs (in this test around 5 VMs).

Here are the logs when error happens:

(1) nova-api logs/traceback:

http://paste.openstack.org/show/116414/

(2) cinder api logs/traceback:

http://paste.openstack.org/show/hbaomc5IVS3mig8z2BWq/

(3) Stats of some connections:
http://paste.openstack.org/show/116425/

As it shown in (3) the issue is not seen with icehouse release.

Can somebody please let me know if it is a known issue?

Hi Nader,

Would you mind pastebin'ing the contents of:

 SHOW FULL PROCESSLIST\G

when executed from the mysql command line client?

That will help to show us which threads are stuck executing what in MySQL.

Best,
