Support » Plugin: W3 Total Cache » Deadlock on Purge (W3TC php-fpm (5.3.19) APC 3.1.9)

  • So, W3TC is the best and I using it on my websites. But I found some bug.

    I use W3TC on WordPress 3.4.2 Multisite and single site. Page cache – disk enchanced, DB cache – APC (User cache), Object cache – APC (User cache). APC.shm_size set to 128M. Php-fpm go to (maybe) deadlock when I try to purge user cache (db, object) by hand or by wp-cron. And then php-fpm not responding, need to restart php-fpm daemon.

    Server software: frontend – nginx 1.3.8, backend – php-fpm (php 5.3.13) + APC 3.1.9 (mmap memory, pthread mutex Locks locking).

    I try to remove memcached (and memcache extension for php) but no luck.

    Any suggestions?

    P.S. Sorry for my bad english 😉
