New Issue: intermittent gasnet error in local UDP configuration

18186, "mppf", "intermittent gasnet error in local UDP configuration", "2021-08-09T18:46:43Z"

Summary of Problem

I'm seeing errors along the lines of

*** FATAL ERROR(Node 0): An active message was returned to sender,
    and trapped by the default returned message handler (handler 0):
Error Code: EBADENDPOINT: Destination endpoint does not exist               
Message type: AM_REQUEST_M
Destination: (127.0.0.1:59597) (1)
Handler: 64
Tag: 0x7f000101000167f3
Arguments(5): 0x00000000  0x00000001  0x00000000  0x00000000  0x00000009  
Aborting...
*** Caught a fatal signal (proc 0): SIGABRT(6)
NOTICE: Before reporting bugs, run with GASNET_BACKTRACE=1 in the environment to generate a backtrace. 
NOTICE: We recommend linking the debug version of GASNet to assist you in resolving this application issue.

I have already tried setting CHPL_MASTERIP and CHPL_WORKERIP but that does not seem to help.

Steps to Reproduce

On my system, which is runing Ubuntu 21.04, with Chapel main (I am on 60571a055b but I have also reproduced it with 1.24), I am able to reproduce with the following commands:

source util/quickstart/setchplenv.bash
export CHPL_COMM=gasnet
make
chpl examples/hello6-taskpar-dist.chpl
for i in `seq 1 10` ; do ./hello6-taskpar-dist -nl 2; done

I have also seen this failure when using qthreads.
I am seeing the failure in something like half of the trials.
