<div dir="ltr"><div>Hi All,</div><div>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: </div><div><br></div><div>MOD_AUTH_CAS: Error parsing XML content for '77a947d79339d3373937985aa1610fgr' (Internal error)</div>
<div><br></div><div>I think the problem lies somewhere in glusterFS configuration and I hope it is resorvable. </div><div>There is no such a problem when I'm using local ext4 FS for mod_auth_cas CASCookiePath directory.</div>
<div><br></div><div>I found a little similar problem here: <a href="http://lists.gnu.org/archive/html/gluster-devel/2010-02/msg00024.html">http://lists.gnu.org/archive/html/gluster-devel/2010-02/msg00024.html</a></div><div>
<br></div><div style>and here: <a href="http://thr3ads.net/gluster-users/2010/05/476790-3.0.4-vs-apache-cookie-looking">http://thr3ads.net/gluster-users/2010/05/476790-3.0.4-vs-apache-cookie-looking</a></div><div><br></div>
<div>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:</div>
<div><br></div><div><cacheEntry xmlns="<a href="http://uconn.edu/cas/mod_auth_cas">http://uconn.edu/cas/mod_auth_cas</a>"></div><div><user>user1</user></div><div><issued>1362730876640545</issued></div>

<div><br></div><div><br></div><div>I was trying a lot of different settings, but with no lucky. Now it's look like this:</div><div><br></div><div>gluster volume info</div><div> </div><div>Volume Name: cas-volume</div>
