quad4map_32bit: rmap ovflo, lost [xxxxx,xxxxx)

This is a new one on me. It's in output of 'dmesg' and in syslog. HP L3000, newly upgraded to 11i.

Anyone...anyone...???

Thanks

quadrant 4 of memory is your shared memory section. The overflow indicates that you ran out of space and the system took some. If you have Glance, go to 't', for system table report, and see if the Shared Mem Table (shmmni) is full. If so, increase the kernel parameter shmmni.

Hope it helps

John

you've got fragmentation in the the 4th quadrant (thus the quad4 portion). I did some looking around and all I can find is that this is where shared objects are located.

The fix that I found

is to increase your shmmni kernel parameter.
