kernel: Out of Memory: Killed process 2990
There is a tomcat webserver running that is used to host a java application. Sometime the service goes down with error logs. I see the following error messages in /var/log/messages:
kernel: Out of Memory: Killed process 2990 (co). Out of Memory: Killed process 25671 (httpd) Out of Memory: Killed process 8914 (httpd). Out of Memory: Killed process 9022 (httpd). Out of Memory: Killed process 3018 (httpd) Can someone guide me what i should do on this and what could be the problem? Thanks, Sandeep |

But the memory results seems to be fine . Please see results below:
free -m total used free shared buffers cached Mem: 2015 2001 14 0 207 1567 -/+ buffers/cache: 226 1789 Swap: 0 0 0 |

2001/2015 is certainly near the limit, especially if you don't have any swap. Do you? (Sorry for asking -- this happened to me recently; swap had somehow failed at boot time and I was wondering why I was running out of memory all the time ...)

The "free" output already suggests that you have zero swap total, though it's hard to see from the space-stripped HTML rendering.
On Linux, swapon -s shows what swap you have active. On other platforms, try "apropos swap". On Solaris, it looks like the command is simply "swap". |
