HP-UX Itanium 11iv2 memory management

HI,

The total amount of memory occupied by the system increase between boot and after a period of utilisation. I believe that it's a dynamic allocation for some table. I would like to know if it's limited to a certain value or percentage. Is it manageable ?

Exemple :
AT BOOT:
Physical memory = 2613616 10.0g 100%
Free memory = 2105000 8.0g 81%
User processes = 136355 532.6m 5% details with -user
System = 356163 1.4g 14%
Kernel = 277755 1.1g 11% kernel text and data
Dynamic Arenas = 115018 449.3m 4% details with -arena
vx_global_kmcac = 32973 128.8m 1%
spinlock = 24622 96.2m 1%
vm_pfn2v_arena = 10372 40.5m 0%
mdep arena = 6569 25.7m 0%
vx_buffer_kmcac = 4832 18.9m 0%
Other arenas = 35650 139.3m 1% details with -arena
Super page pool = 14929 58.3m 1% details with -kas
Static Tables = 114451 447.1m 4% details with -static
pfdat = 61256 239.3m 2%
vhpt = 16384 64.0m 1%
bufhash = 8192 32.0m 0% bufcache hash headers
text = 8037 31.4m 0% vmunix text section
nbuf = 7008 27.4m 0% bufcache headers
Other tables = 13573 53.0m 1% details with -static
Buffer cache = 78408 306.3m 3% details with -bufcache
UFC file mrg = 0 0.0 0%
UFC meta mrg = 0 0.0 0%


AFTER A WHILE:
Physical memory = 2613616 10.0g 100%
Free memory = 1908408 7.3g 73%
User processes = 136092 531.6m 5% details with -user

vx_buffer_kmcac = 33120 129.4m 1%
vx_rwsleeplock_ = 17265 67.4m 1%
vm_pfn2v_arena = 10372 40.5m 0%
Other arenas = 53641 209.5m 2% details with -arena
Super page pool = 27478 107.3m 1% details with -kas
Static Tables = 114451 447.1m 4% details with -static
pfdat = 61256 239.3m 2%
vhpt = 16384 64.0m 1%
bufhash = 8192 32.0m 0% bufcache hash headers
text = 8037 31.4m 0% vmunix text section
nbuf = 7008 27.4m 0% bufcache headers

Buffer cache = 78408 306.3m 3% details with -bufcache

Thanks.
