systemd services do not use ulimit, so you need to check "systemctl show pacemaker.service" for any clues. I have seen similar error in SLES 12 SP2 when the maximum tasks was reduced and we were hitting the limit.

But memory is always enough. This is virtual machine with Linux 4.14.35-1818.4.7.el7uek.x86_64 and pacemaker 1.1.19-8.el7_6.4 corosync 2.4.3-4.el7 (all from linux repository). Please, help us to resolve this problem with “Cannot allocate memory”. May be we need some additional settings on OS or upgrade to fresh pacemaker/corosync version where this issue resolved or some other? -- WBR, Andrey Larionov _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/ _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
