I've got some perl code that uses shared memory up and running,
the problem is that I can't have more than 10 segments, ever.
Here's an example sequence:
% perl test
915133603-512
...
915133613-512
could not share: LE::Object=HASH(0x152db0), No space left on device at
/usr/le/lib/LE/Object.pm line 264.
Segmentation fault (core dumped)
"could not share:..." is my error from a die() call, 'No space
left on device' is the given system error. And the seg fault, well,
that's defiantly not *my* fault ;-). Thinking that I needed more
shared memory I promptly rebuild my kernel with the following
parameters:
# This provides support for System V shared memory.
#
options SYSVSHM # enable for memory
options SYSVSEM # enable for semaphores
options SYSVMSG # enable for messaging
options SHMMAXPGS=8192 # 32MB of sharable memory
options SHMMNI=4096 # more shared memory identifiers
options SHMSEG=1024 # shared memory segs/process
Which seems to work pretty well:
% ipcs -M
shminfo:
shmmax: 33554432 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 4096 (max number of shared memory identifiers)
shmseg: 1024 (max shared memory segments per process)
shmall: 8192 (max amount of shared memory in pages)
Does anyone out there know which device is running out of space,
and how I give it more?
Many thanks,
Alf Watt
