dmesg error

himacs — Fri, 01 May 2009 03:26:05 GMT

Hi Admins,

B.11.23 server shows below error while dmesg

How i can solve this?

Deferred swap reservation failure pid: 4077
Deferred swap reservation failure pid: 4077
Deferred swap reservation failure pid: 4077

Pid 4077 was killed due to failure in writing the signal context- possible stack overflow.
Deferred swap reservation failure pid: 6585
Deferred swap reservation failure pid: 6585
Deferred swap reservation failure pid: 6585

regards,

Hi Himacs,

Processes with pid 4077 and pid 6585 are trying to reserve swap spaces but are failing.
Possibly you might be running out of swap.

Check memory usage by:
swapinfo -tam

If this is the case you need to add the swap space.

Regds,
R.K.

Hi,
Unfortunately, you're running out of swap space. You don't have reserve so you have to add swap space or stop some process.

Hi,

yes your system is running out of swap memory as per the swapinfo -tam
only 4% and 8% are free.
add more swap memory

From your swapinfo'2 output missing "memory" line, the first thing you should do is to enable pseudo-swap. See swapmem_on(5).
