This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Patch(es) available in kernel-2.6.18-261.el5 You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5 Detailed testing feedback is always welcomed. Reproduced on -238 kernel, with simple reproducer attached which open 2048 files and fork children increasingly. On -238 kernel I got the following from dmesg allocation failed: out of vmalloc space - use vmalloc=<size> to increase size. On -261 kernel, the reproducer can exit normally. You should modify the open file limit first [root@localhost ~]# sysctl -a | grep fs.file-max fs.file-max = 294829 [root@localhost ~]# ulimit -n 294829 [root@localhost 681586-out-of-vmalloc-space]# uname -a Linux localhost.localdomain 2.6.18-261.el5 #1 SMP Thu May 12 16:46:44 EDT 2011 i686 i686 i386 GNU/Linux [root@localhost 681586-out-of-vmalloc-space]# ./reproducer 15 [root@localhost 681586-out-of-vmalloc-space]# dmesg <======== No error msg here Created attachment 499110 [details]
