System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel x86

Operating System (example: Linux 2.0.26 ELF) : BSD/OS 4.0.1

PostgreSQL version (example: PostgreSQL-7.0): PostgreSQL-7.0.2

Compiler used (example: gcc 2.8.0) : gcc version 2.7.2.1

Please enter a FULL description of your problem:
------------------------------------------------

Here are some corrections for the BSD/OS port. BSD/OS doesn't define
LC_MESSAGES, so that needs to be ifdef'd, and the kernel tuning
parameters are incomplete and suboptimal.

+ You may need to increase the number of sysv semaphores.
+ PostgreSQL 7 allowing the default number of backend connections
+ allocates 32 semaphores, which is just over half the default system
+ total of 60.
+
+ The defaults are in /sys/sys/sem.h:
+
+ /* Configuration parameters */
+ #ifndef SEMMNI
+ #define SEMMNI 10 /* # of semaphore identifiers */
+ #endif
+ #ifndef SEMMNS
+ #define SEMMNS 60 /* # of semaphores in system */
+ #endif
+ #ifndef SEMUME
+ #define SEMUME 10 /* max # of undo entries per process */
+ #endif
+ #ifndef SEMMNU
+ #define SEMMNU 30 /* # of undo structures in system */
+ #endif
+
+ Set the values you want in your kernel config file, e.g.:
+
+ options "SEMMNI=40"
+ options "SEMMNS=240"
+ options "SEMUME=40"
+ options "SEMMNU=120"
+
+ ---------------------------------------------------------------------------
+
Increase SHMMAXPGS by 1024 for every additional 4MB of shared
memory:

/sys/sys/shm.h:69:#define SHMMAXPGS 1024 /* max hardware pages...

The default setting of 1024 is for a maximum of 4MB of shared memory.
+ PostgresSQL 7 allowing the default number of backend connections
+ allocates about 1.2MB of shared memory.
+
+ Enclose the above line with "#ifndef SHMMAXPGS" and "#endif", and in
+ your kernel config file set the desired value, e.g.:
+
+ options "SHMMAXPGS=8192"

For those running 4.1 or later, just recompile the kernel and reboot.
For those running earlier releases, there are more steps outlined below.

This is computed dynamically at bootup.

$ bpatch -r sysptsize
! 0x9 = 9

! Next, change SYSPTSIZE to a hard-coded value. Use the bpatch value,
! plus add 1 for every additional 4MB of shared memory you desire.

/sys/i386/i386/i386_param.c:28:#define SYSPTSIZE 0 /* dynamically...

sysptsize can not be changed by sysctl on the fly.
