Random cache miss without any purge

  • Resolved David

    Hi,

    It seems there is an issue with caching on all of my website using LSCache.

    Here’s what’s happening: When my website is crawled, it is cached initially. However, after a certain period—sometimes a day, sometimes just a few hours—all previously cached posts return an “x-litespeed-cache: miss” status.

    I’ve tried disabling some plugins that I suspected might interfere with LSCache, such as Related Posts and IQ Block Country, but the problem persists.

    Regarding the logs, since our site receives a high volume of visitors, I didn’t enable logging for all posts. Instead, I activated logging for just one post in the “Debug URI Includes” section. After some time, the status of that post changed from “hit” to “miss,” but the purge log did not indicate any purging activities for that specific post.

    From my understanding, it seems that the posts are changing to “miss” status without any purging occurring.

    I’ve been struggling with this issue for over a week and genuinely don’t know what else to do to resolve it.

    it won’t work that way if you use debug include URI , if other action triggered , it wont show up

    you can set it to Admin IP Only

    this way it won’t generate log for other IP but only IPs in the list , you can put a fake IP there or just 127.0.0.1, and purge log has its own entry will keep generate no matter the IP set

    Thank you for your advice, this is the Purge log I’m getting, it seems random posts getting purged by admin-ajax.php. During this short period nothing has been edited or posted on the site.

    Additionally, there are still other posts that are not recorded in the log that are being purged as well.

    okay, the purge log is half way

    now please set debug log to ON , debug include URI to admin-ajax.php , see if it can capture the full log

    Thread Starter David

    (@miladk)

    There are now many logs being generated (about 10 logs every minute). Which one should I focus on and share here?

    you can search `

    X-LiteSpeed-Purge

    in debug log , and share the section it matches

    if you have quite some traffic then you may need to set the log size to bigger

    if you set it to bigger, you may need to use SSH or similar tools to check log , open it in log view for big file will cause it time out or browser hangs

    It appears that the wp-content/debug.log file is not being generated.

    In the admin panel, the log history is quite limited and does not display previous entries.

    Plugin Support qtwrk

    (@qtwrk)

    it should be within /wp-content/litespeed/debug/

    I have disabled any plugins that triggered a cache purge, and now there are no purge logs appearing.

    However, after 1 to 2 hours, every crawled page still changes from ” x-litespeed-cache: hit” to “x-litespeed-cache: miss.”

    The only logs still being generated are from the Ad Inserter plugin, which displays ads based on geo-targeting, which I send above.

    it seems not same case , the admin-ajax.php in previous reply has no “Query String” , but the last one you posted does have and have no purge call

    try use the purge log tag as reference (the 3 digital after IP:port) , to search in debug log to get full log

    I apologize if I didn’t explain this clearly:

    I found only this type of log in the purge log, which indicates that the WPDiscuz plugin caused some posts to get purged.
    I already disabled the WPDiscuz plugin yesterday after I found this out:

    After disabling the WPDiscuz plugin no more purge logs are generated besides the default WP comment ones which get triggered every time someone comments on a post:

    But even after disabling the WP Discuz plugin, after 1 to2 hours (or 6 hours if I purge all the cache beforehand), every crawled post —regardless of whether there are only 10 or 2,000 posts being cached — still changes from “x-litespeed-cache: hit” to “x-litespeed-cache: miss,” without any purge logs being generated.

    The only logs still being generated are primarily these two which are no purge logs. The first log is getting generated every time a non-cached post is being opened by a browser, the second one is generated when a cached post is being opened by a browser:

    it looks like wp discuz did the purge , I assume something like a new comment is posted ?

    It seems so, but the problem isn’t the wp discuz plugin anymore, since i have disabled it yesterday as i explained above and still all of my cached pages turnes from hit to miss

    For example, I just opened this specific post that was cached 2 hours ago, and it has changed from “x-litespeed-cache: hit” to “x-litespeed-cache: miss” without any purge log being generated in the last 2 hours:

    This is the debug log:
