Ok, next step then:
The OP wrote the problem was when creating a new thread.
From some obscure sources (personal knowledge, reading, wild guess, ...)
we assume it might be a system call "pthread_create()" which is used for
this.
So we do a "man pthread_create" and get (quoted from my Linux machine):
| NAME
| pthread_create - thread creation
Looks good! Continuing reading that page, we arrive at (again, from Linux):
| ERRORS
| The pthread_create() function shall fail if:
|
| EAGAIN The system lacked the necessary resources to create
another thread, or the system-imposed
| limit on the total number of threads in a process
{PTHREAD_THREADS_MAX} would be exceeded.
|
I leave it to the OP (or other users of his system, FreeBSD 7.1) to
1) check the man page there for the exact description when
"pthread_create()" might cause error EAGAIN,
2) find out which resources that might be, or which system limit, and
how to check more, maybe even change the limits.

Thanks :)
I never claimed it wouldn't be files, I just said that using the errno
value reported will help in the analysis (and tried to explain how to do
that).
But if somebody finds that the message
"*1135: Can't create a new thread (errno 35); if you are not out of
available memory, you can consult the manual for a possible
OS-dependent bug*"
really is caused by a file limit, I propose to report a bug about a
misleading error message.

Jörg
