Memory segments

[Hugo Wilhelmus]

I do a ipcs -mbob and see (part):

m 11793 .. D-rw-rw-rw owner group 31 4290772992

This memory-segment is Deleted but there are still 31 process attached. It is not possible
to delete this segment without cousing any trouble to the system ? Can one see what 31 process are attached ? Do they actual use this segment ?

Hi,

Your memory segment is flagged for deletion [see the upper case D in the flags] but it won't go away until the 31 processes attached to it are done.

You'll probably need a tool like Glance or lsof to actually figure out what processes have attached to that memory segment.

Are these possibly httpd processes? Apache will leave a "dead" memory segment like this. Run ps -ef|grep httpd|wc -l. If it equals 31, then thats the source...

Hi,

Use the attached shminfo.sh to find out the processes attached to the shared memory segment.

Once downloaded in to ur system, run the script which will extract a binary.

# /root/tools/shminfo -s 11793

Hello Sundar,

Can't get your attachment ... !
Is it possible to put the source
directly into your message ?
