Subject: Re: IPC::Shareable: Could not create semaphore set
I am getting somewhere now!!
If I call 'tie' after I have created the hash, all is fine.
Surely I should be able to create the shares memory and then add/remove
entries in the hash at will!?

Hello
I have had a good look round at what may be causing the error..
Could not create semaphore set: No space left on device
What I am basically doing is the following...
tie %myhash, 'IPC::Shareable', hashkey, {create = 1, exclusive = 0,
mode = 0666, destroy = 1, size = 262144 };
while($dstIP = $sth1-fetchrow())
{
print $dstIP\n;
$myhash{$dstIP}{dispatched} = time();
$myhash{$dstIP}{response} = 0;
$myhash{$dstIP}{num_polls} = 1;
$myhash{$dstIP}{action} = 0;
}
When I start up the process, I manage to print out 10 $dstIP addresses
and then I get the error. This is rather a small amount of data to fit
into 262144 bytes. Even if I increase this size, I get the same error at
the same point. Without setting SHM fetchrow returns 20 $dstIP addresses
and they print fine.
Any ideas

Re: IPC::Shareable: Could not create semaphore set
Actually, $dstIP prints out 10 times. and the maximum number of shares
mem segments is 10.
Maybe its the hash that isn't declared correctly!?

Re: IPC::Shareable: Could not create semaphore set
I meant semaphores...
from 'sysdef -i' I get
* IPC Semaphores
*
10 semaphore identifiers (SEMMNI)
60 semaphores in system (SEMMNS)
30 undo structures in system (SEMMNU)
25 max semaphores per id (SEMMSL)
10 max operations per semop call (SEMOPM)
10 max undo entries per process (SEMUME)
32767 semaphore maximum value (SEMVMX)
16384 adjust on exit max value (SEMAEM)
