Lars, 

The changes between 2.6.1 and 2.6.2 were confined to a small number of 
changes in 30 perl modules in /home/httpd/lib/perl/Apache, and I would not 
expect any of those changes to impact daemons started by 
/etc/init.d/loncontrol 

Is there any information in the log files in /home/httpd/perl/logs, e.g., 
in: 

lonmemcached_errors
lonsql_errors
lonc_errors
lond_errors 

What is reported by: 

ps aux |grep memcached 

As I recall you are running SuSE 10.2.  Upgrade to LON-CAPA 2.6.2 worked for 
me without trouble on SuSE 10.2 (32 bit) when I tried it, and I've also 
upgraded all the MSU production servers to LON-CAPA 2.6.2 (a mix of Linux 
distros/architectures) without incident over the past two days. 

Have you needed to update any SuSE packages recently? (Look for logs in 
/var/log/YaST2).
