XF 1.5 memcached Errors

[Arno Nühm]

I get these errors sometimes, maybe 1-2 times a day:

ErrorException: MemcachePool::get(): Server localhost (tcp 11211, udp 0) failed with: Malformed VALUE header (0) - library/Zend/Cache/Backend/Memcached.php:180

#0 [internal function]: XenForo_Application::handlePhpError(8, 'MemcachePool::g...', '/var/www/domain...', 180, Array)

#2 /var/www/domain.com/htdocs/library/Zend/Cache/Core.php(303): Zend_Cache_Backend_Memcached->load('xf_data_styles', false)

#6 /var/www/domain.com/htdocs/index.php(13): XenForo_FrontController->run()
#7 {main}

Any idea?

Sounds like there are read issues with Memcached. Is the Memcached server being restarted unexpectedly?
