Error description
DMS timeout might occur when amepat is running on the only available CPU on the system. All the other CPUs are folded and amepat has monopolized the only online CPU in the system Stack trace will be something like pvthread+0F2200 STACK: [0005F480]begfst+000200 () [0005F47C]begfst+0001FC () [001327E0]vm_cmem_get_ref_stats+000100 (??)

Local fix
To circumvent this issue, make sure that there is always an extra CPU available. This can be achieved by the following command schedo -p -o vpm_xvcpus=2 NOTE: this still might not protect from a situation where HATDS or similar process is bound to this particular CPU where 'amepat' command is running
Problem summary
A heartbeat or other realtime process will incorrectly signal a failure.
Problem conclusion
Insert a manual scheduler check during statistics processing.
Temporary fix
