GLib-ERROR **: Cannot create pipe main loop wake-up

sheree.boman

Hi!

Setup openvpn

[OpenVPN 2.3.6 x86_64-redhat-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [PKCS11] [MH] [IPv6] built on Dec  2 2014]

on red hat server

[Linux xxx 2.6.32-279.19.1.el6.x86_64 #1 SMP Sat Nov 24 14:35:28 EST 2012 x86_64 x86_64 x86_64 GNU/Linux]

Quite a simple setup, basic certificate and PAM authentication.
TCP connections
no LZO
PAM authentication in addition to certificates.

After a few days of server running, users complained about inability to connect to openvpn anymore and relevant entry from debug log looked like this:

GLib-ERROR **: Cannot create pipe main loop wake-up: Too many open files

Any ideas how to troubleshoot?

I have the same problem.

Any Ideas?

i have exactly the same problem...
OpenVPN 2.3.6 under CentOS 6.6

I'm using the plugin for PAM auth. It seems to be a bug of the plugin itself, where it opens files for each session but doesn't colse them after the clients disconnect.

Any ideas?
