Check you mysql running or not.
try restarting mysql server
For LINUX Machine
"sudo /etc/init.d/mysql restart'

OR you can set 'max_allowed_packet=500M' for mysql to solved it and not repeat in future.

I have set ini_set('max_allowed_packet','500M'); in settings.php , but no change in above error .
some times this page also showing following error ,

PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT alias FROM {url_alias} WHERE source = :source AND language IN (:language, :language_none) ORDER BY language ASC, pid DESC; Array ( [:source] => user/1/edit [:language] => en [:language_none] => und ) in drupal_lookup_path() (line 150 of C:\xampp\htdocs\LifeEcho\includes\path.inc).

If you are on LINUX machine
Edit following file.
/etc/mysql/my.cnf to set 'max_allowed_packet = 512M'
Restart MYSQL

Remove your previous changes from settings.php

I disabled the toolbar module and it is now working fine for me. I am anyways using the Admin menu module for administration menu.
