appserver - error 9407

Hello,

Our configuration : AIX 4.3 - Progress 9.1d SP 06 - stateless appserver

Since a few weeks we have regulary (almost daily) the following error in the appserver server log :

[03/11/19@10:26:43.824+0100] P-270662 T-000000 0 AS -- Connection failure for host loopback port 61872 transport TCP. (9407)

Sometimes the appserver performs a shutdown; sometimes the processes remain running, but they are inaccesable. A kill -1 then terminates the "bad" processes. We just cannot find out where port numner 61872 is coming from. (This port number seems to be dynamic, as it changes for every process, but it remains in the range of 61800 - 61900.

I changed port ranges from both broker & server to a higher level, to avoid conflicts with some other processes, but till now I have no results on this.

Does anyone has an idea of what could be going wrong?
 
Good news! We found out that the problem was the jit-compiler. I found in my archive that there was a problem with 9.1B and the jit-compiler on AIX. I did the same as a few years ago and disabled the jit-compiler. Since then, neither of the appservers crashed again.
