RAM memory consuption 100%

[Alessandro Potenziani]

Dear guys,

from 2 days we're experiencing a sad behaviour on our L2000 box.
Performing a swapinfo -tma the result shows 100% of RAM consuption but we have no process running on it except DataProtector 5.5 server and cell manager.
In addition a message showing: prngd[2108]: Could not fork: Not enough space is present on system log.
The swap memory is at 100% but if we add another swap volume the RAM seems to become used at about 15%. Issuing a sar -v 1 5 shows nproc inod end nfile are not full.

Any ideas,

Thanks,
Alessandro

Alessandro!

Looks like you are swapping way too much for the "could not fork" error.
Please send us the output for swapinfo -tam and vmstat 5 20 please to analized those and be able to give you some direction.

Regards,

Jaime.

Now we are trying to reconfigure swap space.
We have a Java application running on this box and it could be possible that the java garbage collector isn't releasing unused memory!
I'll take you informed.
