You are running a very old version that is out of support and this looks very much like a very old bug that was fixed long ago. The solution is to upgrade to a supported version that has the fix.

I know we need to upgrade to a supported version. But it need some time to plan to upgrafe. Before that, we would like to know what the bug is. In case we still keep using 9.40, we won't hit the bug again. thanks in advance, Fan >You are running a very old version that is out of support and this looks >very much like a very old bug that was fixed long ago.

You wrote: Hi, all informix IDS9.40 FC7XO occur Recursive Exception error ¡Athen system crashed. there is no AF file. What is Recursive Exception error ? Any ideas about the case and solution ? Response: The recursive exception error means that 1 thread encountered a signal that was going to bring the server offline, and then in the process of trying to report the problem the server received a 2nd signal (the signals I'm referring to would likely be SEGV or BUS). At which point, it just hard aborts the server to get it offline rather then looping in the signal handling code forever. The problem is that because the server received a 2nd signal while trying to process the 1st one, none of the diagnostic information the server normally provides in the AF file exists because the engine wasn't able to get to the point where it reports that info yet. So unfortunately, because the AF file isn't complete there is very little way to tell what cause the 1st signal. So without engaging tech support, there is not going to be much to tell you what caused the problem and what the solution is because in this type of failure, it's very difficult to tell what was happening at the time of the AF. Generally speaking though if you have been running this version of the product for a long time and this is the 1st time you've seen this type of failure, I'd ask you if you recently changed anything at the application level or server, which may be what triggered this. As it's somewhat unusual for this to start happening out of the blue. Jacques Renaut IBM Informix Advanced Support APD Team
