Earlier I was getting dvz shoutbox msgs in error log so I removed that. But still I am facing the same problems.Can anyone will please help me out?

Thanks in advance.

The SQL errors may be related to limits or performance issues with database server (https://dev.mysql.com/doc/refman/8.0/en/gone-away.html) - you host support should be able to help or determine what's happening.

Parser output validation failed is an unrelated, minor warning - it looks like there are redundant </em></strong> HTML tags in Username Style values of some user groups that should be removed.
