Memory leak issue, possibly because PHP APC add on.

I noticed that when I enabled APC it spawn so many apache process and it can consume memory really quickly. Our client server crashed twice because it ran out of memory.

Setup:
Linux CentOS 7
MariaDB
Apache 2.2
php 5.4.16 with APC
enabled JSMIN.
CPU : 4 cores
RAM : 12 GB

When I disabled the APC add on I didn't have that many apache processes being spawned and the RAM is hardly go beyond 3GB. I was doing a mass update that update the Account record and ALL of its related records, this is a massive operations but it didn't go beyond 3GB in terms of memory use when I have the APC disabled.

When I turned it on it was easily jumped from 2 GB to 6 GB.
is there a known issues with APC add on that you guys are aware off?

  • Hi Alex,
    I am glad and not so glad to hear that. I thought I am the only one having this issue.
    Although on that bug report, it says it reported on version 7.5.2.1 while our customer is on 7.5.1.0 does it matter?

  • I understand. It is always a good news/bad news scenario -- bad that it is happening, good that we are aware of it and looking to address it. 

    The reported version does not matter in this case. That is just so we know a minimum version where it is occurring, but it is not indicative of what version will contain the fix. 
  • We see this issue a lot when using APC and making Studio changes.  I hope it gets fixed soon!
