Gretting EBADF when doing accept on a socket

Did you find a soultion for this problem?

We have a application which uses Orbix that is exhibiting the same symptoms. If the application is linked with the MT version of the Orbix library the accept fails with errno = EBADF. If the application is linked with the single threaded version of the Orbix library the accept succeeds. In fact, the accept() will fail if the application is linked with the MT version of the library. It does not have to invoke any orbix functions.

I didn't receive an answer. I can't remember if I put the part ib about later would do a close on the sockect fd and don't get an error. This is a java based app

tusc may have side effects which cause the accept() to fail. I tried runnig tusc on my example program and it failed during the accept returning EBADF as a return code. The program works if I do not use tusc.


I have attached the test program source as well as the tusc output. I use telnet for a client.

[John Weaver]

That is good to know. The reason we ran tusc was because the app. was failing in the first place :(

Try patch PHKL_22840. It should fix the problem.

I have seen this error message when the ARPA patch was installed without all of it's dependencies. It only seemed to affect multithreaded application that was in development and accept() seemed to be the only call that failed.
