Error description
When a single transaction deletes a large number of rows which have cascade deletes and triggers that execute UDRs, the target node seems to consume/leak huge amounts of memory in CDRD pool. On an informix instance setup with small SHMTOTAL such as 500mb the delete causes an Out of Memory situation. The memory consumption can be seen by running "onstat -g mem" as shown below: IBM Informix Dynamic Server Version 12.10.UC5W1X3 -- On-Line -- Up 01:35:19 -- 525620 Kbytes Pool Summary: name class addr totalsize freesize #allocfrag #freefrag CDRD_1 V 48435028 384778240 71947352 1560302 55105
