Hi. I was trying to update to perl-5.8.5 on my NetBSD 2.0.1 sparc64
using pkg-src2004Q4. However, multiple SysV/IPC tests fail on setget().
I found that if the ext/IPC/SysV/sem.t test allocates 10 semephores,
right away with the "No space left on device" error. If I lower it to
tests pass (after adjusting the presumptions of the other tests about
of semaphores there are).
I looked at my kernel config, and have:
## System V compatible IPC subsystem. (msgctl(2), semctl(2), and
options SYSVMSG # System V message queues
options SYSVSEM # System V semaphores
options SYSVSHM # System V shared memory
#options SHMMAXPGS=1024 # 1024 pages is the default
options P1003_1B_SEMAPHORE # p1003.1b semaphore support
I tried raising SHMMAXPGS to 2048, but that didn't affect it.
Anyone know why this is happening? Is it a sparc64 problem, or
just some poor allocation of resources problem in the kernel I'm
using? Or a perl problem?
This perl package (pkgsrc-2004Q4 i386 2.0.1) works just fine there,
all the tests. To the best of my knowledge, the above-mentioned section
of the kernel config is unmodified on that machine...
