From PHP info are you able to tell me what PHP extensions are installed? Just a full copy and paste with any manual sensoring you want to do would help most. My guess is this host may have a higher base memory usage due to a large number of PHP extensions, plus more memory due to being 64 bit. In any case I can try and replicate a similar environment and do testing. |

What's this command say? php -r 'echo memory_get_usage();'; |

Mentioned this to my hosting company today but no response yet. I also just purchased better hosting so hopefully that will help avoid this kind of thing. I've got loads of bespoke CDN options on this new account which look exciting but may conflict with Composr, so that will be fun to experiment with :D Hopefully I can get v11 on there, white screened on my previous account after installing :) |

Ok, so I've got a fix for this coming, but first I will explain the situation. This took me some time to properly dig into. Composr defines a bare minimum memory of 32M for PHP's memory_limit setting. It recommends 64M and actively tries to set 64M at startup. This host seems to be imposing a limit of 40M that cannot be overridden. It 'should' work, because Composr with all non-bundled extensions works on 32M on my dev machine, but the large number of PHP extensions on your server may be causing additional memory use, or there may be other factors. I have made some optimisations and have it working on 26M on my machine now. The main one is a cheat, if Composr detects a low memory limit then it will no longer render the admin menus so deep. That uses a relatively large amount of memory as it has to dig into all the module files to spider out the menu. I do want to note that since 2006 PHP has had a default memory limit of 128M (https://github.com/php/php-src/commit/3ffc1c8f4a1e4c1658f94038e009e226258a65a4). a 40M limit that you cannot override is painful to see, assuming you didn't have some kind of control panel option to change that. Note that memory limits may produce inconsistent problems, as the cache state of Composr is going to vary a lot as you go. Generally speaking, if Composr has cached stuff already then it will use less memory. |

Automated response: Memory optimisation Make a number of improvements to Composr's memory debugging ability, and optimisations to support servers with lower memory limits. |

Fixed in git commit 423fa2b96 (https://gitlab.com/composr-foundation/composr/commit/423fa2b96 - link will become active once code pushed to GitLab) A hotfix (a TAR of files to upload) has been uploaded to this issue. These files are made to the latest intra-version state (i.e. may roll in earlier fixes too if made to the same files) - so only upload files newer than what you have already. If there are files in a hot-fix that you don't have then they probably relate to addons that you don't have installed and should be skipped. Always take backups of files you are replacing or keep a copy of the manual installer for your version, and only apply fixes you need. These hotfixes are not necessarily reliable or well supported. Not sure how to extract TAR files to your Windows computer? Try 7-zip (http://www.7-zip.org/). hotfix-4305, 2020-07-02 11pm.tar (538,624 bytes) |
