[SSI-devel] Problems with shared memory segements

[Andreas <ro...@co...>]

Hello.

I have a problem with the use of shared memory segements on openSSI. I 
have a cluster with two nodes. I create a shm-segment on node 2 (1 is 
initnode) and do some read/write operations on it from node 1. While 
accessing the shm I reboot node 2. Of course the process on node 1 gets 
an error.

The problem I have is that after node 2 is away it is not possible to 
create a new shm segment ( not on node 1 and not on node 2 after it 
cames up again).

shmget return -1 and errno is set to ENOSPC (no space for a new segment)

Hava anybody an idea what the problem could be?
