Exception: Unable to obtain lock for session (retry in 30s)

I experience issue when viewing my page.

So sorry… Error: Exception: Unable to obtain lock for session (retry in 30s) (in wire/modules/Session/SessionHandlerDB/SessionHandlerDB.module line 96)

#0 [internal function]: SessionHandlerDB->read('fj818rmpnqntp4f...')
#1 wire/core/Session.php (330): session_start(Array)
#2 wire/core/Wire.php (413): Session->___init()
#3 wire/core/WireHooks.php (968): Wire->_callMethod('___init', Array)
#4 wire/core/Wire.php (484): WireHooks->runHooks(Object(Session), 'init', Array)
#5 wire/core/Session.php (205): Wire->__call('init', Array)
#6 wire/core/ProcessWire.php (602): Session->__construct(Object(ProcessWire))
#7 wire/core/ProcessWire.php (316): ProcessWire->load(Object(Config))
#8 index.php (52): ProcessWire->__construct(Object(Config))
#9 {main}

This error message was shown because: site is in debug mode. ($config->debug = true; => site/config.php). Error has been logged.

Do you have any idea why this is happening?
