Hi,
I have just encounter a strange problem about our UNIX programming.
When I use fork() to produce a son process and let the son process to
do a function cminit()(cpi-c program), an error occurs:
Sendsig: can't grow stack. sig 11,pc=0x34345355
When I let father process to do this function, there is no problem. Can
someone give me some advice about that? I think it's strange. Because
this same c program can run on HP-UX and IBM AIX with no problem. If
you know, pls let me know as soon as possible. We are now competing
with HP and IBM now. We do the customer application on our Alpha in
order to compete with them.
Thanks in advance.

Just that it runs on HP or AIX doesn't indicate that is doesn't have errors/features. What's the program, can you reduce the problem to a small sample, or provide a ptr to the source. The PC doesn't look to good, and it seems that the code trampolines until the stacklimit is reached where it than SegV's. If you can't provide a ptr to the source, run it with ladebug and take a look at the stack when it dumps core. under ladebug use set to enable catchforks, so that you can switch between the copies.

Actually, the signal it's trying to deliver is a SEGV.
So you're getting a recursive SEGV that's eating up the stack.
Something like that. The suggestion to run this under the
debugger is good one. So good you must have tried it already....

Do you have a wait() routine ? Is the process defunct ?

Hi,
There is no wait() routine. Only have a call to wait a
queue(msgrcv()) to get message. Yes the process can't go further after
receiving the sig 11.

Could be that DEC UNIX is not cleaning house ???
send a snippet of your source here or email me.
