Random "key does not exist on the server" messages

Configuration:

PhpFastCache version: 7.0.0-alpha
PHP version: 7.1.11
Operating system: Windows 2012 Datacentre

Issue description:

Using couchbase server as a memcached server, I'm getting rare, but random errors:

Error Message: Uncaught Couchbase\Exception: LCB_KEY_ENOENT: The key does not exist on the server in W:\web\assets\plugins\phpFastCache.v7\src\phpFastCache\Drivers\Couchbase\Driver.php:128

Error Line: 128

By default, keys are set to expire after 600 seconds, and I'm getting around 100,000 page views a day on the server with around 10 cached requests per page - I'm going to guess it's a resource / memory issue - but should driver.php gracefully handle the non-existent key or error out as above?

Thanks G!

Hello,

Do you reproduce this bug with the V6 (final) ?

Also I may need to access and/or collaborate with your project on this bug since it appears to be really specific if you don't mind.

Cheers,
Georges

I'm gonna push a fix for that, do you have any time to test it in real time with me ?

[rdecourtney]

Hi G.. yes of course :-) I'm devving all day today - it has only been a random issue though that I can't reproduce, but I can push an update and then monitor over the next few days if that helps?

[Geolim4]

Yes of course, I'll give you a patch in a moment

[Geolim4]

Okay I'll push a fix tonight !
Thanks you !

Not exactly, I did the commit from my work company ;)
I'll fix my computer tonight anyway, the hardest part was to retrieve my gpg signature to sign the commits above ;)
