Comment 4 for bug 693415

<Yasufumi> At Jenkins, cannot we confirm the reason? It should be fail to allocate shm
 "fail to allocate shm" is depend on system. if not allocated, shm should fail.
<stewart> Yasufumi, yes, I verified on local Ubuntu too. the default kernel configuration for Ubuntu isn't adequate for what we ask.
* stewart forgets what that is... hopefully I put it in the bug report
<Yasufumi> /sbin/sysctl -a | grep shm ?
<stewart> good idea
* stewart tries that
<KAlexey> shmmax / shmall
 see also https://bugs.launchpad.net/percona-server/+bug/693415
<stewart> kernel.shmmax = 33554432
 kernel.shmall = 2097152
 kernel.shmmni = 4096
 (on laptop)
<Yasufumi> kernel.shmmax = 18446744073709551615
 kernel.shmall = 1152921504606846720
 kernel.shmmni = 4096
 (SuSE 11.2)
<stewart> small difference
 only by many many orders of magnitude :)
