MEMORY LEAK IN ER CDRGTX# POOL WHEN LOADING OR DELETING DATA ON A TABLE WITH A LONG ROW SIZE TABLE. | |
| product: | |
IBM IDS ENTRP E / 5724L2304 / B15 - IDS 11.50 | |
| Problem description: | |
A memory leak can be seen in the CDRGtx# memory pool (where #
represents a number), when inserting or deleting data on a
replicated table with a long row length.
The online.log may show the dynamic allocation of shared memory
as a result. For example:
10:32:47 Memory sizes:resident:116736 KB, virtual:150528 KB, no
SHMTOTAL limit
10:32:50 Requested shared memory segment size rounded from
50000KB to 50176KB
10:32:50 Dynamically allocated new virtual shared memory
segment (size 50176KB)
10:32:50 Memory sizes:resident:116736 KB, virtual:200704 KB, no
SHMTOTAL limit
Running the following command will show the CDRGTx pool
increasing in size over time:
% onstat -g mem -r 1 | grep CDRGtx
CDRGtx0 V 113880040 5574656 346248
171 171
CDRGtx0 V 113880040 17207296 1051480
