Warning:system call pthread_create failed.

[Neelesh Tripathi_1]

Hi,
I am trying to run some java application on HPUX 11i I have java 1.4.0
I get the following error
Warning:system call pthread_create failed.
return value: 11
errno: 22
parameter:thread = 4a
attr = 48
start_routine = 7aea8656
arg = a402f0
startup java.lang.OutOfMemoryError: unable to create new native thread

Do I need to change any kernel parameters or any pathes that are required for the same

Can anyone help me

Thanks
neelesh

i would gradually try increasing these kernel params

maxdsiz (for 32 bit applications)
maxssiz
maxtsiz
maxdsiz_64(64 bit applications)
maxssiz_64
maxtsiz_64
Also,
max_thread_proc
nkthread

Just check the present values for these above KP.

I'm sure that was due to hitting the limit imposed by the nkthreads kernel parameter. Please increase this kernel tunable.

If you were hitting nkthread I'd expect a lot more to be going wrong! My money is on max_thread_proc, which controls the number of threads any one process can create. This is a very common one for java programs.

I would start by increasing max_thread_proc alone.

You asked about patches.

In addition to installing the latest patch bundles, you will need PHCO_29109 for 11i.
