Subject: [cl-muproc-devel] [CL-MUPROC] Troubles with threads in SBCL
Message-ID: <1419cd92815.-5586757855426236814.-2633628203557585563@zoho.com>

Hi all

I'm new with cl-muproc. Playing with cl-muproc, I've got strange trouble. SBCL cannot create more, than about 600 threads.

Here is simple code, which I use to get this error:

(defun newmuproc ()
       (muproc-spawn (gensym)
             (lambda ()
             (mumsg-receive (from)
               ((terminated reason) t
                (muproc-log-errorstream
                 "Got termination from ~a: ~a.~%" terminated reason))
               ((test)
                (muproc-log-errorstream "Got value ~a.~%" test)))
             (muproc-log-errorstream "Done.~%"))
             nil
             :trap-exits t
             :errorstream *trace-output*))

(dotimes (i 1000) (newmuproc))

Could not create a new thread.
   [Condition of type SIMPLE-ERROR]

Restarts:
 0: [RETRY] Retry SLIME REPL evaluation request.
 1: [*ABORT] Return to SLIME's top level.
 2: [ABORT] Abort thread (#&lt;THREAD "new-repl-thread" RUNNING {BF89CB1}&gt;)

; Evaluation aborted on #&lt;SIMPLE-ERROR "Could not create a new thread." {B604149}&gt;.

(length (muproc-all-processes))
584

sbcl --version
SBCL 1.0.57.0.debian

Best regards Alexander aka 'CosmonauT' Vynnyk
