Hylafax and "No response to MPS"
- by Joril
We have an Hylafax 5.2.5 CentOS 5 installation hosted inside a Xen
virtual machine. It works quite well, but now I'm in the process of
upgrading/migrating it to a KVM virtual machine running Ubuntu 10.04 and
Hylafax 5.5.1 (compiled from source using
http://sourceforge.net/projects/hylafax/files/hylafax%20debian%20build%20files/
)
The problem I'm having is that - while receiving works fine - sending
faxes is extremely unreliable, I get lots of "No response to MPS
repeated 3 tries", or "Failure to transmit clean ECM image data."
The line, modem and configuration files I'm using are the same as
before, so I thought that it could be a KVM scheduling issue, but even
setting cpu_shares to 10240 instead of 1024 doesn't change a thing...
What else could I try?
Here's an example log file http://pastebin.com/cN01cpEs
