Problem IT20684
|
Status: Closed |
MUTEX RELATED MEMORY LEAK IN MT POOL
|
| product: |
IFMX ULT WHSE E / IM0019BOS / C10 - IDS 12.10 |
| Problem description: |
After the Informix server has been running for a while the
amount of memory allocated to the mt memory pool may become very
large and continue to grow. This can be seen using the onstat -g
mem command.
By comparing successive outputs from the onstat -g amx command
it can be seen that the number of mutexes for "sqscb->spa_cache"
continues to grow. This can be observed with the command:
onstat -g amx | awk '{print $3}' | sort | uniq -c | sort -rn
For example:
2077 sqscb->spa_cache
1226 centry
429 AIOreq
293 hash
244 pctypecache
244 pccastcache
128 gfile
...
This problem is similar to, but distinct from, APAR IT19869. |
