Not able to see all objects under a folder. Communication failure occuring!

[Gunnu131]

In pimcore there are 1 crore objects . When i click on the folder to show in grid view it shows error:

Timestamp: Fri Nov 08 2024 10:02:01 GMT+0530 (India Standard Time)
Status: 0 | communication failure
URL: /admin/object/grid-proxy?classId=1&folderId=41419&xaction=read&_dc=1731040291645
Method: POST
Message:

1.) I have increased Innodb buffer pool size to 46G
2.) Increased Global wait timeout, read time etc...
3.) Enable slow query log technique and when i click on folder to retrieve info It was showing:

Time: 2024-11-08T04:46:48.085146Z
User@Host: hostname Id: 162

SET timestamp=1731041165;
SELECT object_2.o_id as o_id, object_2.o_type as o_type FROM object_2 WHERE (o_path = '/Assets/FOLDER' OR o_path LIKE '/Assets/FOLDER/%') AND object_2.o_type IN ('object','folder') ORDER BY o_id ASC LIMIT 25;

SELECT COUNT(*) FROM object_2 WHERE (o_path = '/Assets/FOLDER' OR o_path LIKE '/Assets/FOLDER/%') AND object_2.o_type IN ('object','folder');

I have put indexing on o_type, o_path, o_classId on objects .

This is my.cnf file:

[mysqld]
bind-address = 0.0.0.0
log-bin=mysql-bin
server-id=1
max_execution_time = 99999999
innodb_buffer_pool_size = 46G
innodb_log_file_size = 1G
innodb_file_per_table = 1
key_buffer_size = 2G
sort_buffer_size = 64M
sort_buffer_size = 64M
tmp_table_size = 64M # Set to 64 MB
max_heap_table_size = 64M # Set to 64 MB
slow_query_log = 1
slow_query_log_file = /var/log/mysql/mysql-slow.log
long_query_time = 1
innodb_flush_method = O_DSYNC
innodb_log_buffer_size = 512M

Nothing worked. Any help or suggestion would be appreciated!
