Since your process is continuing (not core dumping, apparently), likely a different permutation. If the system call is blocking the signal we are using, we may not be able to remedy for you. If you need to progress this issue, please provide your test case, UniData version, platform, os version to your UniData support provider. Also - readmes are publicly available on the Product Availability Matrix - regarding fixed issues. https://u2tc.rocketsoftware.com/matrix.asp regards, Wally Terhune U2 Support Architect Rocket Software 4700 S.

According to our IT policy, we are not actually allowed to divulge any details on what software versions, etc, we are using. That's why I simply posted a message asking if anyone knew anything offhand. Being relatively new to the U2 style of through ISV support, when issues are detected with previous releases (then fixed), are they only available through the readme's of later releases or are notifications passed down through the food chain? Obviously having to wait for and then scan the readme's of each new release is a slow of tedious method of finding out about potential issues with your system. I can see how our signalling issue would fit into this, but "was run at the moment the target udt process was freeing shared memory" doesn't make sense when the process is sitting waiting at a blocking call for pipes? Is this a different issue or was this all fixed as part of that?

From the readme: Issue 11687 - Problem Description UniData -- When using the PORT.STATUS command with the PID option to review the CALL.STACK or another udt process, the target udt process may have abnormally terminated and produced a core file. This occurred if the PORT.STATUS command was run at the moment the target udt process was freeing shared memory. This problem has been fixed.

I was running some tests and discovered that doing a "PORT.STATUS PID pid CALL.STACK" on a program that is waiting to open a named pipe with OSOPEN caused it to bomb out. I looked and it didn't have an ON ERROR statement, so I added it and checked again. Every time I made the PORT.STATUS call, it caused it to drop into the ON ERROR section. My guess would be to perform the check on the program; it has to interrupt it, hence causing it to bomb out of any blocking calls. Until now, I had assumed the PORT.STATUS command would not affect a program, but now it appears that it can, meaning it could potentially be dangerous to use in a production environment. Is this documented anywhere?
