ftp - memory fault (coredump)

[S.Rider]

When ftp'ing out from a couple servers, ftp get/put fails with a "memory fault (cvoredump). I can ftp from other servers into these servers without issues.
Users say it started yesterday morning - no changes had been made before that.

Hello Jay,
There are a number of updates to the ftp client in the itrc patch database.

Also the server.

Can you tell me what OS and client the users were using?

It happens just ftp'ing between a couple 11.11 servers. Both were patched in October with a Customized-patch-Bundle we got from our HP engineer.

Jay -- check your patches.

Also check the "core" files with "file core" to see if this gives you more clues.

What OS revision do you have and what do you get if you do:

swlist -l product | grep -i ftp

the suggestion to look for the core files is very good - see if you can load them into a debugger and get a stack trace.

if the memory dumps are happening consistently, you might try tuscing the FTP client to see what the last system calls before failure might have been.

perhaps the client code has a malloc somewhere that is ass-u-me-ing it always succedes and isn't and your systems have gotten under some memory pressure or something - or maybe swap pressure. just a wag

This type of problem is almost resolved by adding patch to system (if it can be resolved at last)
