This suggests that eviction policy for cache FAILOVERMARKER is not set properly (set to NULL vs. LRU) so that the new record insertion fails.

workflow execution failed with the error message - ERROR: com.tibco.as.space.ASException: LIMIT_EXCEEDED (capacity_exceeded)

Product: TIBCO MDM 8.x, 9.x Operating System: All OS supported by MDM Database: All databases supported by MDM App server: All App servers supported by MDM

In CacheConfig.xml file, set FAILOVERMARKER cache Eviction policy to LRU (<EvictionPolicy>LRU</EvictionPolicy>) so that the least recently used record are deleted and new record is inserted:
 <Cache>
            <Name>FAILOVERMARKER</Name>
            <Description>To detect if a task needs to be repeated. Should never be evicted. </Description>
            <Type>distributed</Type>
            <SingleByteObjectSize>44</SingleByteObjectSize>
            <MultiByteObjectSize>44</MultiByteObjectSize>
            <ListSize>800</ListSize>
            <EvictionPolicy>LRU</EvictionPolicy>
 </Cache>
