its happen every time I serve large file from reverse proxy and getting a "413 Request Entity Too Large" from openlitespeed and then the crash happen

it says core dumped but I checked and no core file created so I don't know exactly how to identify the issue

RGdevz commented 2 years ago

its also happen outside proxy, basically every time response exceed the Max Dynamic Response Body Size and we get code 413 the server crash edit: the crash not happen on version 1.7.14, might be affecting non arm build too, didn't tested

How did you compile it for arm ?

Build ols and php from source than syslink lsphp bin to ols bin folder path and to the admin bin folder path

The core files should be located in /tmp/lshttpd/bak_core. Please make sure /tmp partition is large enough. You can change core file location with /proc/sys/kernel/core_pattern . Some system uses systemd to manage core file, you can check coredumpctl command.

the problem is that I see the folder get created everytime the server crash but no core file is created, maybe issue with it begin ARM machine? anyway I am using openlitespeed 1.7.14 where this not crashing for now

I do have enough space and I don't have coredumpctl on the system
