MySQL crash while mysqldump / mysqlcheck

everytime I try to backup or check all tables mysql server crashes on Windows server 2012, I am using XAMPP stack for my development environment. The database crypto has more then 1100+ tables in DB. I am including the logs below.

InnoDB: End of page dump 2017-09-24 13:58:35 7dc InnoDB: uncompressed page, stored checksum in field1 2521749199, calculated checksums for field1: crc32 2344073126, innodb 1121903210, none 3735928559, stored checksum in field2 0, calculated checksums for field2: crc32 2344073126, innodb 2892594725, none 3735928559, page LSN 0 2936733816, low 4 bytes of LSN at page end 0, page number (if stored to page already) 34, space id (if created with >= MySQL-4.1.1 and stored already) 1767 InnoDB: page type 17855 meaning INDEX InnoDB: Page may be an index page where index id is 1522 InnoDB: (index "PRIMARY" of table "crypto"."300-token") 2017-09-24 13:58:35 2012 [ERROR] InnoDB: It is also possible that your operatingsystem has corrupted its own file cache. 2017-09-24 13:58:35 2012 [ERROR] InnoDB: and rebooting your computer removes the error. 2017-09-24 13:58:35 2012 [ERROR] InnoDB: If the corrupt page is an index page you can also try to 2017-09-24 13:58:35 2012 [ERROR] InnoDB: fix the corruption by dumping, dropping, and reimporting 2017-09-24 13:58:35 2012 [ERROR] InnoDB: the corrupt table.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.

We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.

Server version: 10.1.22-MariaDB key_buffer_size=16777216 read_buffer_size=262144 max_used_connections=1 max_threads=1001 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 787106 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0 Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... mysqld.exe!my_parameter_handler() mysqld.exe!my_wildcmp_mb_bin() mysqld.exe!?save_in_result_field@Item@@UAEX_N@Z() mysqld.exe!?save_in_result_field@Item@@UAEX_N@Z() mysqld.exe!?save_in_result_field@Item@@UAEX_N@Z() mysqld.exe!?save_in_result_field@Item@@UAEX_N@Z() mysqld.exe!?save_in_result_field@Item@@UAEX_N@Z() KERNEL32.DLL!BaseThreadInitThunk() ntdll.dll!RtlInitializeExceptionChain() ntdll.dll!RtlInitializeExceptionChain() The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains information that should help you find out what is causing the crash.

I hope someone will help me out Thanks.

From this content in your question, "Server version: 10.1.22-MariaDB key_buffer_size=16777216 read_buffer_size=262144 max_used_connections=1 max_threads=1001 thread_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 787106 K ...."

with max_threads=1001 clue above - check for max_connections in your my.ini or .cnf. Lowering max_connections to = 100 may or may not help get you past the BaseThreadInitThunk() ntdll.dll!
