Users of my WSPR Watch app have been reporting problems over the last day. It looks like WSPRnet.org is down with a database error. "PDOException: SQLSTATE[HY000]  Too many connections in lock_may_be_available (line 167 of /data/var/www/drupal-7.98/includes/lock.inc)."
Unfortunately, my error handling code is looking for a connection error but is failing to pick this up and fails silently as if there's no new data.
WSPRnet handles a huge amount of traffic and I hope they're able to fix this soon.
