Out of memory exception on Varnish 2.1.5

[Connor Walls]

Hi,

We've recently been having problems with varnish being killed with out of memory problems, our logs show information like this:

Aug 22 10:56:17 ip-10-87-13-87 kernel: [4050442.556330] varnishd invoked oom-killer: gfp_mask=0x280da, order=0, oom_adj=0
Aug 22 10:56:17 ip-10-87-13-87 kernel: [4050442.556336] varnishd cpuset=/ mems_allowed=0
Aug 22 10:56:17 ip-10-87-13-87 kernel: [4050442.556340] Pid: 17729, comm: varnishd Not tainted 2.6.32-312-ec2 #24-Ubuntu
Aug 22 10:56:17 ip-10-87-13-87 kernel: [4050442.556342] Call Trace:

Now, we've been planning from Varnish 2.1.5 to 3.0 for a while, and we're hoping that this will solve our issues, but I just want to check if there are known OOM issues in 2.1.5, or is the problem likely to persist after upgrading to 3.0?

Thanks,
Connor Walls
