[Gluster-users] mod_auth_cas+GlusterFS - Error parsing XML content for

Hi All,
I'm using glusterFS (3.3.1) to replicate mod_auth_cas cookie-files between
two Reverse proxy servers. Yesterday, I saw this in logs:

MOD_AUTH_CAS: Error parsing XML content for
'77a947d79339d3373937985aa1610fgr' (Internal error)

I think the problem lies somewhere in glusterFS configuration and I hope it
is resorvable.
There is no such a problem when I'm using local ext4 FS for mod_auth_cas
CASCookiePath directory.

I found a little similar problem here:

and here:

mod_auth_cas reads and writes small cookiefile every time the new HTTP
request comes to protected /location. If there are a lot of concurrent HTTP
requests, there is a moment when Apache can't read this cookie file. The
file looks like this:

<cacheEntry xmlns="http://uconn.edu/cas/mod_auth_cas">
<secure />

I was trying a lot of different settings, but with no lucky. Now it's look
like this:

gluster volume info

Any ideas how to solve the problem?

Thanks for your answers.
