I'm running into issues after upgrading from mysql 5.5 to mysql ver 14.14 distrib 5.7.16 on CentOS Linux release 7.2.1511 (Core)
mysql systemd: Stopping user-0.slice.
mysql kernel: mysqld invoked oom-killer: gfp_mask=0x280da, order=0, oom_score_adj=0

dmesg

Should I need to change innodb_log_file_size = 1000M to 25% of innodb_buffer_pool_size=12G ?
Any help would be much appreciated!

General recommendations:
Control warning line(s) into /var/log/mysqld.log file
Control error line(s) into /var/log/mysqld.log file
Run OPTIMIZE TABLE to defragment tables for better performance
OPTIMIZE TABLE prod.qc_connector_log; -- can free 1479 MB
OPTIMIZE TABLE prod.transport_object; -- can free 1038 MB
Total freed space after theses OPTIMIZE TABLE : 2517 Mb
Set up a Secure Password for user@host ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
Restrict Host for user@% to user@SpecificDNSorIp
MySQL started within last 24 hours - recommendations may be inaccurate
Adjust your join queries to always utilize indexes
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Beware that open_files_limit (40000) variable
should be greater than table_open_cache (1520)
Variables to adjust:
sort_buffer_size (> 256K)
read_rnd_buffer_size (> 256K)
join_buffer_size (> 256.0K, or always use indexes with joins)
table_open_cache (> 1520)
innodb_buffer_pool_size (>= 7638G) if possible.
innodb_log_file_size should be equals to 1/4 of buffer pool size (=3G) if possible.
innodb_buffer_pool_instances(=12)
There is IOWAIT, AFAIK this is not the reason of the crashes.
