The swap space paging activity on this system is extremely high.
|
- Brief random peak in workload or a sustained and increasing workload.
- Application failures, such as memory leaks, causing resource constraints.
|
Find the specific processes that are using an inordinate amount of real memory and remediate if thrashing is persistent.
Check /var/log/messages for signs of hardware or software failures.
If system thrashing is random and not persistent, consider spreading the swap space across multiple physical disks.
If possible, consider upgrading the system to use faster hard-drives. If the increase in swapping is due to valid workload increases, increase the amount of system real memory (RAM).
