Randomly generating 404 pages for random users.

[aftabnaveed]

Since the issue was closed here, I am reopening it, https://github.com/GordonLesti/Lesti_Fpc/issues/74 I don't think the problem with cache has been resolved yet, I still get random category 404 Not Found pages, in fact same category would be served from the cache for one user but it won't for other and it is happening randomly.

As a temporary solution I disabled the catalog_category_view from being cached, but it would be great if we can find a permanent solution for this.

@aftabnaveed did you have tried this logging https://github.com/GordonLesti/Lesti_Fpc/issues/74#issuecomment-61955786 I haven't enough information about this bug and I can't reproduce it. Can that bug be related to this one https://gordonlesti.com/lestifpc/comment-page-13/#comment-21326 ?

Hi @GordonLesti thanks for getting back on this, I included the log code, lets see what happens now, and no its not related to the issue you mentioned, I used redis previously, I thought it could be redis, so I made it file based, I will get back here when I have some more info

Hi @GordonLesti here is the log content

These categories basically exists /catalog/category/view/id/94 but why would it still log it? :S

@GordonLesti would you know the issue yet, did that log output help you? Please let me know what other information I can provide to take out the bug.

@aftabnaveed that is spooky:) that means, that your shop creates 404 pages with the wrong status code. Did you know a modul that can cause that? Maybe we can go a little bit deeper if we log with debug_backtrace? What did you think?

Hi, same here on CE 1.7.0.2 Redis and hhvm. Random categories and subs give default no-route page. Turned fpc off for several weeks but that's not the solution ;) Multi store environment. 8GB mem on vps. Host think that fpc is loading the mem full. When you save a broken category it will work fine. Can't get finger on it. when you flush cache it looks like the problem don't exist but when Redis mem is build up to 1,6GB it will create 1 till 3 random broken links in the menu. Hope we can find a link because i like fpc on. It goes fasterrrr ;)
