Hello mailing list, Earlier today I had Eclipse/Tomcat crash and thereafter I was unable to use ps or other process utilities. Specifically, the output of ps, top, w, and so on would hang and I was unable to terminate the process. `ps` (with no arguments) and `pstree` remained working, however. After some discussion in my distro-specific IRC channel, someone suggested I should reach out to this mailing list.
I am using Arch Linux on kernel 3.10.7-1-ARCH SMP PREEMPT x86_64 Here is the output of `strace ps aux`: http://pastebin.com/jaFCN3YL (large text file) And the output of /proc/<pid>/stack: [<ffffffff81279a64>] call_rwsem_down_read_failed+0x14/0x30 [<ffffffff8114cdb2>] __access_remote_vm+0x42/0x1c0 [<ffffffff8114d240>] access_process_vm+0x50/0x70 [<ffffffff811f069a>] proc_pid_cmdline+0x8a/0x120 [<ffffffff811ef57f>] proc_info_read+0x8f/0xe0 [<ffffffff8118b148>] vfs_read+0x98/0x170 [<ffffffff8118bc39>] SyS_read+0x49/0xa0 [<ffffffff814cfaef>] tracesys+0xe1/0xe6 [<ffffffffffffffff>] 0xffffffffffffffff When I tried to reboot, the system crashed. As I had no good way to collect the contents of the dump, I took a few pictures (the widescreen necessitated two pictures, though I doubt the latter is of much use) and hosted them on imgur: http://imgur.com/a/cqfOH. I hope this information is suitable and that I have not posted here in error. Please keep in mind that I am not subscribed to this mailing list.
