Default memcached threads are not set to 4

If you have Filr configured in a clustered setup (i.e. more than one Filr appliances), memcached is enabled with only 1 thread. It is recommended that the default setting for the memcached threads should be increased to 4.

On each Filr node in the cluster:

1. Stop memcached
   rcmemcached stop
2. Edit the file /etc/sysconfig/memcached and modify the following line:
   MEMCACHED_PARAMS="-m 1024 -d -l server.domainname"
   to add a -t 4 to the parameters as follows:
   MEMCACHED_PARAMS="-m 1024 -t 4 -d -l server.domainname"
3. Save your changes from step 2 to /etc/sysconfig/memcached
4. Start memcached
   rcmemcached start
