Known problems and workarounds
This section discusses problems and workarounds for HP PRM Version C.03.04.
Degraded performance when starting via RC scripts
Issue When an initial configuration requesting memory management is loaded
(after installing or resetting PRM), PRM initializes memory resource groups
(MRGs) giving all usable memory to PRM_SYS initially. Any free memory is
then distributed to other PRM groups. This distribution of memory for use
by your PRM groups can be affected by:
• Heavy paging or swapping
• A single application using over half the lockable memory on the system
Such conditions may exist if memory-intensive applications start
immediately after PRM is configured—as may be the case with applications
starting automatically at reboot.
Workaround You can possibly avoid these issues by:
• Starting these applications in their designated PRM groups with the
prmrun command
• Using the PRM_SLEEP variable in your /etc/rc.config.d/prm file so that the
application manager and memory manager can place processes in their
configured groups before the heavy demand begins.
Application hangs in FSS group with capping enabled
Issue
On HP-UX 11i v2 (B.11.23), an application inside an FSS group may hang
when running in a single-processor virtual partition, nPartition, or system if
CPU capping is enabled.
Workaround
Install patch PHKL_33052.
