    I have w3tc pro and I am having an issue when enabling object caching using memcached. The memcached items seem to be continuously increasing. items keep increasing for hours in a continuous pattern. The object cache expiry is set to no more than 200s

    I tried enabling stats for w3tc and flush count seems to be too low. What could be the issue ?

    Only page cache is enabled other than this and it uses a very small number of memcached items. DB and fragment caching is off.

    Hello Taofik,

    Thank you for reaching out, and thanks for using W3 Total Cache. I am happy to assist you with this.
    Can you please share the screenshot of the Performance>Object Cache settings?
    WHere are you pulling the info in the provided screenshot from?
    Also, is the option Store transients in database enabled in Performance>Object Cache?


    Hello, thank you

    Screenshot is from AWS ElasticCache (memcached).Previously I had page and db cache enabled and item count doesnt reach 200k but after enabling object cache (and disabling db cache) it keeps increasing just like the screenshot until the memcached server stops responding.

    Advanced options:

    Group settings is as default
    Store transients in database is enabled as you can see

    Looking forward to your response, thank you

    plugin version 2.1.1

    Hello taofik,

    Thank you for the information.
    As I can see you enabled the Binary protocol box. The binary protocol can increase throughput.
    Can you please try disabling the Binary protocol and check if the Memcache usage is increasing?


    Thanks for your response

    Sure i will try
    But binary protocol for db cache is enabled with no issues fyi

    Ill try and let you know
