Sep 6 12:23:13 marooned crmd: notice: crm_ipc_prepare: Message exceeds the configured ipc limit (51200 bytes), consider configuring PCMK_ipc_buffer to 140720 or higher to avoid compression overheads
these messages already explain the issue. The configured cluster cib is too big for the default IPC Buffer. The cluster will deal with this by compressing the cib and circumvent this issue. If however the compressed cib would ever be too big for the IPC Buffer then the cluster could encounter a real issue. Also with compression there is an overhead.
on all cluster nodes. Please keep in mind that the above setting of 204800 is just a suggestion and might be not sufficient on the cluster affected. It can be increased further. A restart of openais is necessary to make this change work.
