In my college we have one Linux Server. We have practical on LINUX OS - C Programming.We are given TELENET login on windows 2000 . There are 60 students & in LINUX server there are 200 TELENET login allowed. But when we are implementing our practical of PARALLEL PROCESSING and NETWORKING in which we have to create shared memory area, processes, threads

--our LINUX server hangs frequently & all terminal are stops responding and server has to be restart.

We are also removing shared memory area created by us frequently.To create shared memory area we are using :

"IPC_PRIVATE, & IPC_CREAT command"

We use command "ipcs -m "which shows all shared memory area created by EVERYONE.

Before this year there were no such kind of problm.

So,what would be the problem & its solution.If u can help in this problem then it will be helpfull to us.

THANKS in advance.
Oh goodness - my IPC knowledge is very rusty, and I don't think I've ever TRIED to do something like this. What I do know however is that you must ensure that your hardware and software are up to the job. Preferably use parity checking with your RAM (BIOS setting), and a reasonably up to date and stable Linux PLATFORM - or possibly even consider using the community edition of Solaris.

What distribution are you using?
