Hi.
(Im am sending this to the "stable" list, because it maybe kernel related.. )
On 9.1-RELEASE I am witnessing lockups of the openldap slapd daemon.
The slapd runs for some days and then hangs, consuming high amounts of CPU.
In this state slapd can only be restarted by SIGKILL.
# procstat -kk 71195
PID TID COMM TDNAME KSTACK
71195 149271 slapd - mi_switch+0x186

__umtx_op_wait+0x68 amd64_syscall+0x546 Xfast_syscall+0xf7
On UFS2 slapd runs fine, without showing the error.
Has anyone else running openldap-server on FreeBSD 9.1 inside a jail seen
similar problems?
I have seen openldap spin the cpu and even run out of memory to get
killed on some of our test systems running ~9.1-rel with zfs. No jails.
I'm not sure what would have put load on our test systems other than
nightly scripts. I had to focus my attention on other servers so I
don't have one to inspect at this point, but I won't be surprised if I
see this in production. Thanks for the tip about it being ZFS related,
and I'll let you know if I find anything out. This is mostly a "me too"
reply.
