FWIW, I also see roughly the same behavior, although my environment is<br>
somewhat different than yours. Previously my pgpool server was<br>
running on RHEL6, however it was migrated to Fedora17 (without<br>
changing the pgpool version). Before the migration the load on the<br>
server was typically less than 1.00. Since migrating the load average<br>
is 30+ (with spikes up to 60 quite often). Yet there's nothing<br>
obvious causing the load. I'm certain something in pgpool is causing<br>
this behavior, because the load drops to 0 during the rare times when<br>
we need to stop pgpool for maintenance.<br></blockquote></div><br>Thanks for the quick reply Lonni. I'm glad to hear that it's not a problem limited to Ubuntu. Like you I suspect it has something to do with the 3.x kernel series. I'm going to be doing some experimentation soon to try to isolate and eliminate this problem. I'll update this thread with my findings.<br>
<br>If anyone else is interested in coordinating efforts, I'd be glad for the help.<br><br>QH<br>
