The server cannot detect the operating system's large page size at startup, blocking allocation of large-page memory and halting MySQL initialization.
MySQL Error 44: EE_FAILED_TO_DETERMINE_LARGE_PAGE_SIZE means the server could not read the OS large page size, so it cannot allocate huge pages. Disable large pages or ensure the OS exposes Hugepagesize to resolve the issue.
Failed to determine large page size. EE_FAILED_TO_DETERMINE_LARGE_PAGE_SIZE was added in 8.0.13.
The error appears during server start when MySQL tries to enable large pages (huge pages) and fails to obtain the operating system's large page size. Since the size is unknown, MySQL refuses to proceed because it cannot safely reserve memory.
The message is thrown by the InnoDB memory manager and stops the instance from starting.
The condition was introduced in MySQL 8.0.13 and is classified as a global engine error.
An OS that does not provide huge page support or hides Hugepagesize in /proc/meminfo triggers the failure. On Windows, GetLargePageMinimum returning 0 causes the same result.
Incorrect or aggressive settings such as innodb_use_large_pages=ON or SUPER user memlock limits set too low can also lead to the error.
Containerized environments may block the required system calls.
Most administrators simply disable large pages by setting innodb_use_large_pages=OFF or AUTO, allowing MySQL to start with normal pages.
If large pages are needed, verify that the OS exposes the page size and that the mysqld user has CAP_IPC_LOCK or memlock privileges.
After correcting the configuration, restart the server and confirm the buffer pool was allocated with the desired page size.
On Linux with Transparent Huge Pages disabled, enabling huge pages without reserving them at boot produces the error. Configure vm.nr_hugepages and re-enable THP to solve it.
In Docker, seccomp profiles may block sysconf calls.
Run the container with --privileged or a relaxed seccomp profile, or disable large pages inside the container.
Keep innodb_use_large_pages at AUTO unless benchmarking proves a benefit. Always test huge page settings in staging before production rollout.
Use monitoring tools or SHOW ENGINE INNODB STATUS to verify large page usage after each upgrade. Scripted health checks in Galaxy can surface the error immediately.
EE_OUT_OF_LARGE_PAGES (45) occurs when size detection works but allocation fails.
EE_CANNOT_ALLOCATE_MEMORY shows a general allocation failure. Handling steps are similar: reduce memory, correct privileges, or disable huge pages.
.
Yes. Set innodb_use_large_pages=OFF and restart. MySQL will work with normal 4K or 8K pages.
Most workloads see negligible impact. Only memory bound, high throughput systems may benefit from huge pages.
Run SHOW ENGINE INNODB STATUS and look for "Using large pages" in the buffer pool section.
Galaxy surfaces startup errors in real time, lets you edit my.cnf snippets with version control, and pushes safe defaults such as AUTO mode.
