Hi all,

One Hp E-45 server hanging . taht time i got following error message..

/usr/lib/dld.sl: Call to mmap() failed - ZEROES /usr/lib/libc.1
/usr/lib/dld.sl: Not enough space
Abort

sh: The fork function failed. There is not enough memory available.
Then, after restarted the server, upto now it is working fine.

i faced last time the problem. after restarting it was ok.

So, Restarting is the only solution or anything else to do?

i attached herewith syslog.log file.

Help me in the case
Thanks in advance

With cheers,
Shankar

My guess is you have run out of swap.

You could try and create some more swap on the fly. run "swapinfo -mt" and see what you get. Add swap with the "swapon" command.

Hi.

I think you are hitting max(dts)size in guess maxdsize kernel parameter. You could increase it. View with sam / kmtune -l -q / sysdef the current settings.

HTH,

Shankar,

You have clearly run out of memory and the system might have been swapping tremendously when this error occured. If you would have executed top, you would have seen two proceses vhand and swapper among the top 10 CPU processes. can execute swapinfo -tam to verify the system has gone out of memory and is swapping processes to the swap disk.

The memory in the system might be too low or there could be some fine tuning of kernel parameters required. What is the total memory in the system and what all applications u are running??

with best wishes

As it clearly indicates that there was no more memory on the machine.Not sure about how much RAM and swap is avaliable.

You should attach OLDsyslog.log
That should give you the the "memory full messages"
