Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 249565184 bytes)

Hi

I have created MR!1 for the issue.

Please review it once.

Thank you

Drupal version: 10.3.13
php version: 8.3.14
Module version: 1.0.2

I tested this on my local Lando environment and did not encounter the memory exhaustion issue, which could be due to differences in PHP memory limits between my setup and your test environment. I have also tested by decreasing the memory_limit to 512M, but I think since I do not have very large entries in the Delay Submit form, I was unable to reproduce the issue. The error likely occurs when handling large form submissions with deeply nested arrays, causing excessive memory usage, especially with

print_r($form_values, TRUE)

, which attempts to log the entire dataset. In this case, the form values are stored as a nested array, where each entry contains an associative array with form_id and delay_time. When tracking a large number of forms, this structure can grow significantly, and logging the entire dataset using print_r() can result in excessive memory consumption, leading to fatal errors. While increasing the PHP memory_limit can help as a temporary workaround, it does not address the root cause, which is inefficient logging of large data structures. This patch resolves the issue by replacing print_r() with

json_encode(array_slice($form_values, 0, 5

), JSON_PARTIAL_OUTPUT_ON_ERROR), limiting the logged data to only the first five entries and ensuring non-array values are properly handled, thereby reducing the risk of excessive memory usage and preventing crashes in environments with strict memory constraints. Even though I haven't personally encountered the issue, I recognize the value of this fix in making logging safer and more efficient. I support this patch and this issue can be move to RTBC.

Thanks all, MR has been approved and included in 1.0.3
