Need to clean the system

Hi all,

I really need to clean an HP-UX system, because we do not have enough memory.

Here is a list of running processes, may you help me by telling me which of them i can kill?

vxfsd - sh - vxsvc - samd - top - psmctd - top - unhashdaemon - statdaemon - top - vxsvc - samd - sh - top - cimserver - memlogd - psmctd - syncer - unhashdaemon - statdaemon - netfmt - swapper - smpsched - smpsched - lvmdevd - lvmdevd - dmprestored - syslogd - rpc.statd - rpc.lockd - automount - inetd - sendmail: - snmpdm - mib2agt - rpcd - cimserver - xntpd - pwgrd - swagentd - telnetd - sh - cclogd - diaglogd - xntpd - pwgrd - diagmond - swagentd - telnetd - sh - cclogd - diaglogd - registrar - nfsd - prngd - krsd - cimserverd - dtlogin - p_client - disk_em - dm_core_hw - sh - dm_memory - ksh - getty - supsched - strmem - strweld - strfreebd - ttisr - ioconfigd - lvmschedd - sblksched - sblksched - lvmattachd - lvmattachd - ptydaemon - nktl_daemon - ntl_reader - rpcbind - nfskd - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - biod - hp_unixagt - trapdestagt - fddi4subagt - cron - envd - emsagent - rpc.mountd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - nfsd - sh - sfd

Re: Need to clean the system

Hi,
After killing some process, you have to know which of them get a lot of memory.
So I suggest you first to kill top process and stop diagnostic. After that if you have less memory pressure, check the sh process.
What is the release, the amount of ram ...

Re: Need to clean the system

Hi,

If swapper and vhand process are active, swapping is happening due to memory bottleneck. Now you need to find which process consumes more memory.

You can use glance or kmeminfo tool(if you have) to find the processes which is using high memory. Then you can decide whether to kill or restart the process.
Best wishes,

Ganesh.

Re: Need to clean the system

According to the results of top command, vxsvc, samd, snpdm, swagentd, cimserver, rpcd are the costliest processes...

Re: Need to clean the system

The purpose of this server is to build our application. (compile...)

Exceptionally, we need to run an application today, a very gourmand application ( using at least 600M ).

------------

The uptime command says that the server is up for 11 days. But i can't restart it now, even if i want too !
