Child processes of a Parent Process occupying socket memory


Dear All,

I am new to this community and this is my first post. I am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished. Regarding this I have a few questions:

1) Is it possible that the child processes that are not finished occupy the socket memory of the parent process and ultimately a point is reached where no socket memory is available to fork new child processes.

2) What is the standard limit of socket memory in linux?

3) What is the fate of such child processes (as I have mentioned above)?

4) How to debug such cases so that the exact problematic area is identified?

Any suggestions on the above would be highly appreciated.

Thanks & Regards

Hi, I would try and open another file. You may have too many files open. If the file fails to open I would study errno.See <errno.h> or use perror to print the message. The book, Understanding Unix/Linux Programming by Bruce Molay is excellent and also Linux System Programming by Robert Love. Hope this helps.
