Version: 1.4.5 Here are my current stats output, but right now the issue is not occurring. I will have to toss out a post once it happens again. stats STAT pid 22821 STAT uptime 10416 STAT time 1298229426 STAT version 1.4.5 STAT pointer_size 64 STAT rusage_user 32.524055 STAT rusage_system 121.877471 STAT curr_connections 843 STAT total_connections 1312 STAT connection_structures 904 STAT cmd_get 196833 STAT cmd_set 19566 STAT cmd_flush 0 STAT get_hits 192557 STAT get_misses 4276 STAT delete_misses 0 STAT delete_hits 0 STAT incr_misses 0 STAT incr_hits 0 STAT decr_misses 0 STAT decr_hits 0 STAT cas_misses 0 STAT cas_hits 0 STAT cas_badval 0 STAT auth_cmds 0 STAT auth_errors 0 STAT bytes_read 1466964195 STAT bytes_written 15148562971 STAT limit_maxbytes 536870912 STAT accepting_conns 1 STAT listen_disabled_num 0 STAT threads 20 STAT conn_yields 0 STAT bytes 2532172 STAT curr_items 2657 STAT total_items 19566 STAT evictions 0 STAT reclaimed 4801 END Thanks!
