IC61740: MEMORY LEAK IN ER CDRGTX# POOL WHEN LOADING OR DELETING DATA ON A TABLE WITH A LONG ROW SIZE TABLE.

APAR status

• Closed as program error.

Error 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
     750 526
