Hello.


OpenEdge10 On IBM AIX 5.2 B50 machine with 1 GB RAM 2 GB swap area
server started with -n 10000


promon:
Shared Memory 106732K Segments 1

0 Servers, 477 Users (477 Local, 0 Remote, 0 Batch),0 Apws

RETURN - repeat, U - continue uninterrupted, Q - quit:



LOG tail:
12:11:36 Usr 478: Login by heniek on /dev/pts/254. (452)
12:11:37 Usr 478: SYSTEM ERROR: Too many subprocesses, cannot fork.
Errno=12 (358)


system attributes:
[ppc/root]$ lsattr -l sys0 -E
keylock normal State of system keylock at boot time False
maxbuf 20 Maximum number of pages in block I/O BUFFER CACHE True
maxmbuf 0 Maximum Kbytes of real memory allowed for MBUFS True
maxuproc 128 Maximum number of PROCESSES allowed per user True


What to do??

with regards

According to the Knowledge Centre:

ID: P846
Title: "Too many subprocesses, cannot fork 358 error - Increase maximum
# of processes in kernel"
Created: 4-Apr-2002 Last Modified: 1-Apr-2003
Status: Verified

Known to occur in:
UNIX

Symptom(s):
Unable to fork a process
SYSTEM ERROR: Too many subprocesses, cannot fork. Errno=<number>. (358)
SYSTEM ERROR: Too many subprocesses, cannot fork. Errno=12. (358)
Errno 12 is ENOMEM - Not enough core or space depending upon UNIX flavor

Cause(s):
Kernel setting is preventing Progress from completeing an action. In
this case, errno=12 indicates that Progress is being limited by the
number of Processes allowed per user.

Fix:
Increase the maximum number of processes system wide or per user
(ulimit) via the UNIX kernel. The kernel parameters governing these
values in the kernel are usually NPROC, MAXPROC or MAXUP. These
parameters may vary between UNIX Operating Systems.

Explanation of parameters:

NPROC
The maximum number of simultaneous processes that the system can run.

MAXPROC, MAXUP

The maximum number of processes that a user (any user ID number) can
have at one time.

OR:

Title: "Too many subprocesses, cannot fork 358 error - insufficient
memory for processes address space"
Created: 19-Feb-2003 Last Modified: 20-Feb-2003
Status: Unverified

Known to occur in:
UNIX

Symptom(s):
Unable to fork a process
SYSTEM ERROR: Too many subprocesses, cannot fork. Errno=<number>. (358)
SYSTEM ERROR: Too many subprocesses, cannot fork. Errno=12. (358)
Errno 12 is ENOMEM - Not enough core or space depending upon UNIX flavor
Increasing NPROC, MAXUP or MAXPROC does not seem to resolve the issue.

Cause(s):
Insufficient memory for processes address space.

Fix:
Increase the amount of memory for processes address space. This can be
done by tuning MAXUMEM, SVMMLIM or HVMMLIM via the UNIX kernel.

Explanation of parameters:

MAXUMEM (superseded by SVMMLIM, HVMMLIM)

The maximum amount of memory that is used to run a process. For System V
3, the parameter limits a process's virtual address space.

SVMMLIM
The soft limit that specifies the maximum address space that can be
mapped
to a process. Attempts to increase a process's address space beyond this
value fails with an ENOMEM error.

HVMMLIM
The maximum or hard limit value of SVMMLIM.

I just re-read your message.. 106MB of shared memory??? Quite possibly
this is the issue.. How many users are you actually going to have on
this box?? Also, personally, I think this box is underspecced with
regards the memory.. 477 users is already using almost all the physical
RAM the machine has..
