Vladmir - I don't see anything odd about the memory utilization, nothing swapping, no huge spike in usage. It does climb slightly, but doesn't look significant at all.
I ran dmesg, not sure how to make sense of it, but does show some segfaults, both with php and httpd. Not sure how to tell if this is related: httpd[24013]: segfault at 00007fff4b88b368 rip 00002b4367a61046 rsp 00007fff4b88b370 error 6 httpd[24522]: segfault at 00007fff4b88b368 rip 00002b4367a61046 rsp 00007fff4b88b370 error 6 httpd[24519]: segfault at 00007fff4b88b368 rip 00002b4367a61046 rsp 00007fff4b88b370 error 6 httpd[32640]: segfault at 00007fff9cf661f0 rip 00002b1a165d121d rsp 00007fff9cf661d0 error 6 php[32216]: segfault at 0000000000000015 rip 00002ae33cc53704 rsp 00007fff71ce6128 error 4 On Tue, Sep 22, 2009 at 6:19 PM, Vladimir Vuksan <[email protected]> wrote: > > Also does dmesg show anything interesting ? > > Neil Sheth wrote: > > I've only got 2 servers hitting this.
