DB error

Hi,

Even though the widget seems to work, I get DB errors in the logging the last couple of days:

[29-Aug-2014 01:17:41 UTC] WordPress database error Deadlock found when trying to get lock; try restarting transaction bij query DELETE FROM wp_options WHERE option_name = '_transient_latest_tweets_xxxxxx_5_1_1_0' gemaakt door require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/themes/themename/index.php'), get_sidebar, locate_template, load_template, require_once('/themes/themename/sidebar-home1.php'), dynamic_sidebar, call_user_func_array, WP_Widget->display_callback, Latest_Tweets_Widget->widget, latest_tweets_render, _twitter_api_cache_get, get_transient, delete_option, W3_Db->query, W3_DbCache->query, W3_DbCallUnderlying->query, W3_Db->query, W3_DbProcessor->query, W3_Db->default_query

Any ideas where this comes from and how to fix it?
