I suspect you've hit an IPC buffer limit. Depending on exactly what went into the SUSE builds, you should have the following environment variables (documentation from /etc/syconfig/pacemaker on RHEL) to play with: # Force use of a particular class of IPC connection # PCMK_ipc_type=shared-mem|socket|posix|sysv # Specify an IPC buffer size in bytes # Useful when connecting to really big clusters that exceed the default 20k buffer # PCMK_ipc_buffer=20480
