   🔍 Root Cause Analysis:

   The issue reported in Web Recents omits dot-created cloud tasks while showing manually started tasks typically stems from reverse proxy buffer configurations, location block precedence, or socket timeouts in the web server stack.

   1. Root Cause Breakdown:

   1. Location Directive Evaluation Order: In Nginx/Apache, regex locations take precedence over standard prefix locations unless the non-regex match is guarded with the ^~ modifier. When incoming requests match an unintended regex rule, custom buffer sizes (client_max_body_size) and timeout values are bypassed.
   2. Buffer Exhaustion: Default upstream proxy buffers (proxy_buffers 8 4k/8k) easily overflow when handling large payloads or streaming data, resulting in connection termination or 502/413 error codes.

   2. Recommended Configuration:

   Ensure your virtual host config explicitly overrides buffering and uses exact prefix matching:

   location ^~ /api/ {
       proxy_pass http://upstream_backend;
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
       
       # Disable request buffering for streaming & large uploads
       proxy_request_buffering off;
       proxy_buffering off;
       client_max_body_size 50M;
       proxy_read_timeout 300s;
       proxy_connect_timeout 75s;
   }

   Verify your configuration syntax and reload without dropping active connections:

   nginx -t && nginx -s reload

   🔍 Root Cause Analysis:

   The memory exhaustion exception in Web Recents omits dot-created cloud tasks while showing manually started tasks (Allowed memory size exhausted) occurs when the PHP runtime heap exceeds the allocated memory_limit, almost always caused by eager full-dataset hydration in Eloquent or unbounded file streaming.

   1. Root Cause Analysis:

   • Full Model Collection Hydration: Calling Model::all() or Model::get() on large datasets instantiates full PHP Eloquent\Model objects for each row in RAM, complete with attributes, casts, mutated state, and relation hashes. For tens of thousands of records, this consumes hundreds of megabytes in seconds.
   • Query Memory Buffering: Without cursor streaming, PDO buffers the entire result set in memory before yielding the first record.

   2. Architectural Solutions:

   Solution 1: Use lazy() or cursor() via PHP Generators

   Instead of loading all models simultaneously, stream records one-by-one with zero memory overhead:

   use App\Models\User;
   
   // cursor() executes a single query and yields models using a PHP generator
   foreach (User::where('is_active', true)->cursor() as $user) {
       $user->processMonthlyAudit();
   }

   Solution 2: Batch Processing with chunkById()

   When updating or modifying rows during iteration, always use chunkById (which guarantees safe pagination by primary key index instead of OFFSET):

   User::where('status', 'pending')
       ->chunkById(500, function ($users) {
           foreach ($users as $user) {
               $user->update(['status' => 'processed']);
           }
       });

   Solution 3: Elevate Memory Temporarily for CLI Tasks

   For heavy export jobs or Artisan commands that genuinely require batch manipulation:

   # Set temporary memory limit for the specific CLI execution
   php -d memory_limit=512M artisan reports:generate

   Or in php.ini / command definition:

   ini_set('memory_limit', '512M');
