Re: [nv-l] [nvcold] memory leak ?

We were really suffering from that here
too. We were rebooting weekly to free paging space. The APAR made a really
big difference for us. There were also a lot of memory leaks in AIX 5.1
at the level they were using here, and paging space problems were reduced
when they got it up to a fairly recent maintenance level. They now have
ML 6 on. Between the two changes it is behaving pretty well.

This should be resolved in Fixpack 2.. The relevant APAR number is IY56958.
I just had a customer with a very similar problem who applied Fixpack 2
and his feedback was that it worked.

| [nv-l] [nvcold] memory leak
? |
|
About once a week I get an alert from ITM advising me "'The percentage
of available swap space is low 49%"
nvcold is always the problem. nmon indicates it has aquired over 1.2G of
memory.
I have a a few rulesets in ESE.automation that judiciously test smartset
membership.
I have re-written many of my custom tools to not use nvUtil.
But still, I have to recycle nvcold about once a week.
The memory use, after a recycle, drops to arond 1M, but over time it will
continue to grow.
If I do not act quickly to recycle nvcold it will core dump, ovwdb will
hang and require comleteley recycing NetView daemons to recover.
Is there a fix for nvcold?
NetView 7.1.4 SP1
AIX 5.2 ML02
Platform: 7026-6H1 (660)
6way 750Mhz
6G RAM 4G paging space
