I am running a siebel database on Db2 V8.2 32 bit with FP10a. The
system went to production a week back. After of couple of days we saw
high memory usage and the system ran out of paging space and crashed.
We had to restart the AIX and we can see the memory slowly climbing up.
On investigation, via svmon, we see db2pfchr taking over a 1 GB of
memory and its slowly increasing.
Why is db2pfchr taking lot of memory ? is this normal ?
There is 3 num_ioservers defined

TIA

You might want to open up a PMR and check with support to see if there
are any APARs that were fixed since fp10 relating to memory and db2pfchr.
