Unlikely. 

The only user limit during the tests was on no.files open (default of 256). 
We have just set it globally to a very high value (99000) in /etc/system.

/etc/system:

set px:px_fabric_die = 0
set px:px_fabric_die_rc_ue = 0
*set px:px_fabric_die_tc_ue_gos = 0
set segmap_percent = 60
*set smallfile = 1572864
set maxpgio = 128
set rlim_fd_max = 260000
set rlim_fd_cur = 99000
set tune_t_fsflushr = 1
set autoup = 60
set shmsys:shminfo_shmmax=0xffffffff
set sq_max_size = 10000
set noexec_user_stack = 1
set noexec_user_stack_log = 1

Then after reboot (soft and hard limits for the user):

-bash-3.00$ ulimit -H -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
open files                    (-n) 260000
pipe size          (512 bytes, -p) 10
stack size            (kbytes, -s) unlimited
cpu time             (seconds, -t) unlimited
max user processes            (-u) 29995
virtual memory        (kbytes, -v) unlimited

-bash-3.00$ ulimit -S -a                                                        
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
open files                    (-n) 99000
pipe size          (512 bytes, -p) 10
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 29995
virtual memory        (kbytes, -v) unlimited
-bash-3.00$ id
uid=101(wof) gid=666(www)
-bash-3.00$ 

We have run truss again. We have the same types of crashes:
_mutex_lock_impl & _malloc_unlocked plus some other
(last time we probably didn't see them as the test was too short?)

One of the threads in one of the crashes now has sig_coredump
so you may want to examine that too.

We attach truss output (in two parts) and stack traces + a summary file.

We used the same tools and same test configuration as before.
