signal 6- resource lost
Hi all,
I run my application on tru64(OSF) machine. In my application, when loading data from database recently after we add more data, it gives the signal 6,resource lost. The following is basic info about my system and the process. Can someone tell me what's
the criteria to issue the signal in the system?
If I remove some of the data from database, the application won't get any signal.
I noticed that the application takes about 25.5% percent of the phyiical memory(pmem)when it gets the signal. The physical memory of my system is 1GB. is there any limit for the one process to take up the physical memory.
Thank you for any comments and suggestions.
please copy to me: tong_wang@efunds.com when you reply.

Re: signal 6- resource lost
Maybe you need bigger memory quota.
Do man sys_attrs_proc.

Re: signal 6- resource lost
Is there any related core file formed there. If so debug that with application binary. Check the new added data also.

Re: signal 6- resource lost
We did get the core file. It seems not much help to me.
When we run on our machine(1GB memeory), we shut down all unnecessary applications, no other terminals connect to this machine.
We did not run with the debuggor. The application stop printting out message on terminal, and it takes several ten seconds to exit. During the period, we have enough time to run top etc.
Please kindly give me the hints what doc I should check and where can I find it. I am not sys adamin.
regards,
Tong

Re: signal 6- resource lost
I've checked out that the stack size is setup as:
per_proc_stack_size = 33554432
Can someone tell me how to check out the stack size in a process? I got the core file.
Thanks & regards,
Tong
