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

Pid 4077 was killed due to failure in writing the signal context- possible stack overflow.

Re: dmesg error


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,

Re: dmesg error

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.

Re: dmesg error

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

Re: dmesg error

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