Redis increase auto logout time

[MaximR]

I have the next configuration in the local.xml file and after ~ 30 minutes customers auto logout.

    <cache>
        <fast_backend>Mage_Cache_Backend_Redis</fast_backend>
        <fast_backend_options>
            <server>127.0.0.1</server>
            <port>6379</port>
            <persistent></persistent>
            <database>0</database>
            <password></password>
            <force_standalone>1</force_standalone>
            <connect_retries>1</connect_retries>
            <read_timeout>10</read_timeout>
            <automatic_cleaning_factor>0</automatic_cleaning_factor>
            <compress_data>1</compress_data>
            <compress_tags>1</compress_tags>
            <compress_threshold>20480</compress_threshold>
            <compression_lib>gzip</compression_lib>
        </fast_backend_options>

        <!-- <slow_backend>database</slow_backend> -->
        <slow_backend>memcached</slow_backend>
        <memcached>
            <servers>
                <server>
                    <host><![CDATA[127.0.0.1]]></host>
                    <port><![CDATA[11211]]></port>
                    <persistent><![CDATA[1]]></persistent>
                </server>
            </servers>
            <compression><![CDATA[0]]></compression>
            <cache_dir><![CDATA[]]></cache_dir>
            <hashed_directory_level><![CDATA[]]></hashed_directory_level>
            <hashed_directory_umask><![CDATA[]]></hashed_directory_umask>
            <file_name_prefix><![CDATA[]]></file_name_prefix>
        </memcached>
    </cache>

If remove this part of configuration customer auto logout time increases to a few hours and more.

How to fix this configuration?

'Cookie Lifetime' is set 86400.

this is your cache configuration not the sessions.

make sure you have php session timeout increased

check php.ini

Thanks,

I changed session.gc_maxlifetime  and it helped.
